.32 H&R Mag J frame and .327 Federal Magnum K Frame

My plan is to have a separate cylinder rechambered to .327 for one of my 16-4's instead of altering the original.

That's probably a good idea given the collectibility of the gun. Some day there will be threads about converted vs. non-converted 16-4s. Shooters will want one and collectors will want the other.

Here's my 16-4 in the middle along with my 17-6 and 14-5.

It wasn't bad enough that my buddy Green Frog is building his own 616, "the gun that never was and Smith should have built", now I had to read this thread!

The .32 is already a favorite caliber of mine with 6 .32 longs and 2 .32 H&R Mags. Now I want a Blue .327 FM K frame.....jeez Louise!
 
Was visiting my LGS where I had purchased my 431 and 432 hoping to find another of that caliber in the display case but the dealer said that S&W stopped selling the 32 Mag in the U.S. as the European market was so hot they were buying all they could ship over there. Not sure about the 327 Mag as I have not been able to find one through any channels except an auction board at very high prices..all5x
 
Hello PoorKnight
I have been a Fan of the .32 H&R Magnum for year's as well as the .32 S&W Long Cartridge. That said I have owned most all of the handguns that S&W has produced in the caliber and still have a Few, that really stand out and perform for me. I sent my S&W Model 16-4 to Bowen a few years ago and had him punch it to The New Federal .327 Magnum caliber. A week after I had it changed over, I took a Large Tennessee Bobcat with it at 35 Yards with one of my Own Hand loads as I could not find any factory ammo for it, so had to roll my own. The Bobcat is currently a Tennessee State record for size and weight as he weighed 41 Pounds dressed out, so if I had to guess I would say that he was well in Excess of 50 Pound's live weight and measured 41" In length. When my revolver was finished Bowen supplied me with 100 cases to reload for it as Factory ammo back then simply did not exist. I settled on a Load using the Sierra 90 Grain Sport's Master bullet with a stiff charge of Accurate Arm's # 5 Powder and a small CCI Pistol Magnum primer. The load when Tested clocked an amazing 1630 F.P.S. out of my 6" barrel. and as shown below was super accurate at the 20 Yard line. I have carried daily a Model 431 P.D. for the past Six years and recently located a nice unfired Model 632 Centennial revolver for my wife. I had only read about these Model 632 Centennial's before buying one for the wife as they only made 1050 of them before discontinuing them, in the early 1990's time span. It came to me in it's original box with the paperwork and tools at a Local gun show from it's original owner. I gave him his full asking price of $275.00 for it, and was Very glad to get it. I also have a Pre-16 K-32 Masterpiece chambered in .32 S&W Long caliber which Shown below which is a Five screw variation that shipped in April 1951 & the Bobcat I Piled up with my Bowen Modified 16-4 Mounted now as well as my current carry gun being my 431 P.D. as well as the wife's Model 632 Centennial. Long live the .32 H&R Magnum and the gun's S&W made to fire it...

This is my 30-1 J frame target conversion with target hammer, trigger and stocks. I'm wondering about punching it out to 32 H&R Mag.

orig.jpg

Make that same gun in a K frame six shot with the adjustable sights and I would be all over one.
 
I got tired of waiting for Smith and Wesson to sell the 32 cal revolvers I was hoping for.

Like you, I purchased a 432 and had a 16-4 reamed to 327 by Mr. Bowen.

In addition I had him build me a 6" K frame in 327 federal using a Model 15 frame, a Model 48 cylinder and barrel from a couple of well used revolvers with very little original bluing left. I don't think my total investment exceeded the cost of a new Smith K frame by more than $100 after I sold the 48 frame.

This is what I ended up with.

samwood,

That's a beautiful piece and the barrel already reads 'Magnum". Or did Bowen re-roll mark the barrel ".327 Magnum"?

Jim,

Thanks. Mr. Bowen re-rollmarked the barrel "327 Fed. Mag. Ctg." My experience with him was first class.

Just added a 431 PD to my .32 collection! Now I have the 16-4, the 632 Pro carry, the 432 and the 431. I'll need to add the 331 now that I know about it. I'll add pics once the 431 comes!

Great bobcat Hammerdown! I owe you some thanks - I read your post on the 16-4 you had converted by Bowen Classic Arms and that's what got me started on the 16-4 - I was already a fan of the .32 H&R. I also REALLY like your 632.

Now I think I'll have to start reloading. With my .32 and .327 revolvers, and the .338-06 elk rifle I'm buying, it is clearly the next step for me.

Hello PoorKnight

I appreciate your kind words. My Model 16-4 has not been roll marked barrel stamped as Federal .327 By Bowen. I wanted to leave the factory stamps original so I Just supplied him with the cylinder & Crane assembly. He had to re-blue my cylinder twice once it was converted so that it's color and shine would match the rest of my gun. It came out nice in the end, but had to be redone by Bowen, which Frustrated him a Little as he does not like to be criticized for his work, but my cylinder did not come close to matching my gun as it looked more like it was Intended for a model 28 Highway Patrolman with it's rather low gloss bluing finish, one good thing was that I live only about 20 Minutes from his shop here in East Tennessee so I did not have to ship my part's or waste time in getting it refinished, as I returned the same day that I got it from him after our phone conversion, and the elapsed time that it took me to return to his shop this time with the gun & cylinder in hand he could see the major difference in the bluing finishes comparing gun frame to cylinder looks.;)





By selling me the 200 Round's of once fired Federal .327 Magnum Brass when I picked up the gun's cylinder, it allowed me to have it with me during my Deer hunting less than a week after it left his shop, which in turn allowed me to Harvest the large Bobcat with it. That Hunting day was one I will Never forget as the Federal .327 Magnum Cartridge really proved itself to me with it's Supreme accuracy and speed as that Big Cat never saw it coming at him, nor never moved once he was hit with the 90 Grain Sierra Sport's Master slug I had hand loaded for it.;) To really see the Federal .327 Magnum cartridge Shine, one must hand load for it to Tailor the load to the gun that it is going to be fired in, I have found my Re-load's do far better than factory ammo in my gun. ;)



I have No Regret's in having my Model 16-4 converted to the Federal .327 Magnum cartridge. It now can fire the following caliber's... .32 S&W, .32 S&W Long, .32 H&R Magnum and the converted Federal .327 Magnum cartridge. I can tell you that after Bowen finished my conversion that my gun actually Grouped tighter with all facet's of the rounds mentioned above and I called and asked him why this was now true of it's performance ? He shared with me that he Matches all of the cylinder throat's when he convert's these gun's to the Federal .327 Magnum and I feel this move alone that he perform's is what attribute's to the guns finer Tack driver accuracy now. Before I had my gun converted I had Taken the .32 H&R Magnum as far as I could go with it. In re-loading for it I was filling the cases to almost a compressed load state with Magnum powder and the load was so Hot that it was blowing the standard Small magnum Pistol primer's Out, so I had to switch over to small Rifle primer's in my starline cases to get further with my velocity of the load's. I can tell you that through all of my hand loading for the .32 H&R Magnum round, that it actually liked the load's hotter and responded with very high accuracy, as I slowly climbed the velocity scale with powder increases. I knew having it switched over to the Federal .327 magnum cartridge would allow me more case room for even higher yet velocity and accuracy potential out of this gun. Put Plainly the S&W model 16-4 can handle anything you load it with due to it's very thick cylinder wall's and it comes through with very accurate target results. ;)



It has been asked several times in the past and even in this Thread if Bowen can convert a Previous .32 S&W Long cartridge revolver over to the new Federal .327 Magnum. I too asked MR. Bowen this question and he simply will not do it nor could he as the cylinder's in those gun's are not long enough to take the entire length of the Federal .327 Magnum. Even if they were long enough to accept the Federal .327 Magnum the gun could not withstand the Huge cartridge Pressure differences between the .32 Long Cartridge round compared to the Federal .327 Magnum. The .32 S&W Long Cartridge SAAMI Pressure is a Mild 15,000 as the .32 H&R Magnum is 21,000 CUP but as we look at the Federal .327 Magnum pressure it has a Huge Major difference being 45,000 P.S.I in case head pressure, so in my eyes an attempt to convert any revolver originally chambered from the time honored .32 S&W Long Cartridge would be a disaster and Major Liability... and the result's would more than Likely be..KA-BOOM...:eek:





As I mentioned earlier in my response, I have had just about every handgun S&W Produced in the .32 H&R Magnum cartridge & at one time I had a Model 331 early on when they were available from the factory and bought it New for $475.00 shipped to my FFL Guy. Shortly after getting it about a Month to be exact, I had a barrel loosening issue with mine. :eek: I had been carrying it daily and went to the range to fire some hand load's of mine through it. When I drew it out of my Holster I heard a weird Rattling noise. I found the actual barrel insert Loose and unscrewed it with my Thumb from it's outer shroud. I then went home and called S&W service to tell them about it and they had me ship it back into them for repairs. They told me that some of the model 331's had this barrel Loosening issue as the machine that Tighten's the barrel into the gun's frame had some issue in getting them tightly in Place & I sure was Glad that day that I did hear that rattle as firing it like that may have been the end of it's life with a Loose Barrel in it's outer shroud. :rolleyes:




While it was at the factory for it's Barrel loosening issues they refinished it as Much of the silver finish had worn off Very prematurely, and I expressed to them that I was not impressed with the gun's finish. :( Once it arrived back home I swapped it off for a model 631 Lady Smith, as a follow up conversation with them in S&W service revealed that these guns have a Machine sprayed on finish :rolleyes: I did not like the idea of carrying a Spray Painted gun, as the service guy told me that they had changed nothing in their guns finish application procedure when they refinished mine for me, so later on he said that I could count on it that the finish would flake off or wear very quickly again. :mad: I had the Model 631 Lady-Smith stainless revolver for almost Five Years before I swapped it off and got my Model 431 P.D. Revolver which I still have and carry daily.




But The Model 431 P.D. Had a Problem with it as well so it too has been back to the factory. Shortly after getting it new in Box, I was cleaning it one day after firing roughly 300 Round's through it when I realized that it had some small Chunk's of it's cylinder Extractor star missing. :confused: I again called S&W service and they sent a shipping label to me for the gun to be returned to them as these missing pieces would not allow proper lock up in battery mode. They replaced my extractor and returned the gun to me and it has been fine since it came back home back in the summer of 2009.








The Model 631 Lady-Smith was a fine shooter but given the fact it was made totaly out of stainless it weighed a Lot more than the Air-Weight's do so I much Prefer carrying my 431 P.D. revolver now, as I got spolied carrying that model 331 Ti-Scan revolver only weighing 11 O.Z. empty the exact same weight of my current carry gun the model 431 P.D. revolver. In the past I also had a Model 631 Kit Gun with a 4" Barrel. I got it brand new in the box as shown, but was Kind of disapointed with it's accuracy Issue. I hand loaded many different load's for it but could never get the gun to settle down to deliver good accurate tight shot group's on Target so it to was traded off, as I am as much a Shooter as I am a collector of these S&W's so if they don't shoot, & Shoot Good good they have to go. :)




There was a huge Magazine article written by John Taffin on these Model 631 Kit Guns where he Tested one when they first came out and he too had accuracy issues with the one that he had used for Testing & Evaluating in that article, so I know it was not just me as far as the gun's accuracy went. :( I have found that the black oxide finish model 431's finish wears much less than the factory's silver finishes did after much carry time, so I am very Pleased with the durability of my Model 431... Here is how my model 331 Looked when I shipped it back to S&W for repairs... along with some Honorable Mentions chambered in .32 H&R Magnum that I have had along the way. :) If you have any question's about these guns I have mentioned feel free to P.M. me here I would be more than happy to tell you how they faired and perhap's keep you from getting something you may not enjoy in the end. I have Liked all of The S&W's I have had chambered in .32 H&R Magnum caliber, but some have done far better than other's as far as shooting goes. Sorry for the Long winded response here, but as you can see I am Very Passionate about the .32 round, and I hope some of my information here is helpful to someone... Hammerdown

Interesting thread! Hammerdown's bobcat is one of the stories that persuaded me to try the .32's. I now have a 432 in .32H&R which is quite pleasant and not too expensive to shoot with low powered .32H&R rounds. It's a backup option to an SP101 in .327 Fed.

(Really like the newer S&W 632 in .327, with a c. 2" bbl, but already had the Ruger when that S&W came out. Maybe next time around...)

Anyway, the strategy is the SP101 as a primary loaded with full power .327 rounds. (GDHP's -- as usual -- look very viable in this caliber.) The 432 is a backup, loaded with Buffalo Bore heavy .32H&R's (or, alternatively, Georgia arms has a fairly warm load for less cost.) A speed strip or two with Buffalo Bore .32H&R's, which will work well in either gun, simplifies reloads if an event should go that far.

Same theory as .38/.357 combos, with generally less recoil, and maybe an extra round or two -- but still plenty of power and (albeit not street proven, yet) effectiveness.
 
Update on "Project 616:" You must use a Model 66 as the base gun to build on. It's the only frame that matches up with the 617 barrel's top rib. I now have a really nice Model 67-1 that I hadn't planned on having. Unfortunately it looks good and shoots very well after replacing damaged grips and sights and it has the nicest out-of-the-box trigger (SA and DA) I've ever found on a stainless Smith. I say "unfortunately" because now I don't want to let it go! :rolleyes:

Barrel is WA and everything else is in OH. Just ordered 1000 rounds of Starline brass which should arrive in about 3 weeks. Oh, the waiting, the waiting! :(

Hello dugo
Glad to see you decided to join us other .32 Nut's here on the exciting Federal .327 Magnum Band wagon. Back when I harvested that large Bob-Cat I had my son in law with me that day. It was his first ever Deer hunt and a day he will never forget. He was more Pumped up about my Bob-Cat harvest than I was, and I was glad he was along for the ride. I have promised him my Bob-Cat mount when I leave this old world, so he can share the stories with my Grand kid's and perhaps their Grand Kids. We Had Learned of this Bob-Cat's existence from our friend who let's us hunt his land for Deer. Apparently it had come up into his back yard twice while he wife was out in the yard during the day time, Which is Not Normal for any Bob-Cat to do, so he asked me to Eliminate it if it crossed my path and I assured him that I would if Given the chance to. A week before Deer season I worked very hard on assembling the correct hunting round for this Ca, and once I arrived at one hole group's out of my S&W by hand loading for it I assured my son in law that if I saw this cat in the woods during our deer hunt that I would drop it in it's Track's with my New then Bowen conversion of the Federal .327 Magnum round that my S&W Model 16-4 Now was. I hand rolled the load for it and shot many of them I thin around 400 round's of it at the range prior to the opening day of Deer season to insure accuracy the day I hunted with it. Oddly, The load I had selected was as scary accurate at 50 Yards as it was at the 25 Yard line with little difference in bullet drop giving me consistent group's the size of a dime if I did my part right. The Sierra 90 Grain Sport's Master Hollow point bullet's that I used in my load sure did their job wel in Harvesting this large Cat but Finding Bullets for the .32 round can be a huge challenge at times these day's. I have Two dozen Boxes of Hornady's XTP's on hand in 85 & 100 Grain weight for hunting as well as some more Sierra's. For serious Target work I have often chose Rainier Ballistic's Lead safe bullets. I like them so much due to their Inherent accuracy Potential that I just ordered 2000 More of them yesterday. Rainier bullet's are double struck so their shape is very close in tollerance. They apply a thin .005" copper flash covering on their bullet's which keep the bore from leading up, yet allow for a medium crimp on the heavier Magnum style loads. They Offer Two Bullets in the .32 H&R Magnum type, one being a flat Point style bullet and the other being a hollow point style bullet, both iare in 100 Grain weight so they pack a serious punch out of the Federal .327 Magnuim Load's. I have recovered some of the Rainier Ballistic slug's from the soft sand Berm at our Range after being fired through my S&W and they actually Mushroom far Better than the Hornady's or Sierra's do in diameter holding most of their weight when they come to rest in the soft sand. I have not tried them for hunting Purposes, but with their supreme accuracy Potential, and Large Mushroom effect I think perhaps this year I will Load some to take along with me Deer hunting with me. With the copper flash coating they have over them and the soft lead construction of the inner bullet I feel they should give Excellent Jack Hammer results on Harvesting Game. Here is a link to Rainier Ballistic's & I Highly suggest that you or other's should give their bullets a work out if you re-load they are a True Blessing as they are moderate in price but Huge on Accuracy & performance. I have Turned on many of my friend's to these Rainier Ballistic Bullet's in the past Five years that I have been using them and all of them have been super satisfied, and many of them that gave up their habit of Frequent shooting due to the higher bullet prices that one has to pay for the Hornady's & Sierra bullet's are now back at the range banging away with these Rainier Bullet's. I even use them in my Pre-25 that is chambered in .45 A.C.P. Caliber of which I chose the 200 Grain Semi Wad cutter bullet design and they give me a one hole ragged group that you can cover with a quarter at the 25 Yard line. Get ya some, they work super and Don't break the bank when you Purchase them...;) Regards, Hammerdown

I have always wanted a Mod 16, (or K32), but have never had the opportunity to buy one and now probably couldn't afford one. I have seen where several have taken and had k Frame .32's made from .22 cal. barrels and cylinders. Why wouldn't it be feasible to have a K38 barrel and chambers sleeved. I did have Dave Chicoine sleeve a 22/32 target for me and it worked well. Is there some technical problem, (like too thin a sleeve barrel) or something that would prevent this? Seems like could be an easier option. (I looked for .22 barrels and cylinders and had no luck finding any.)

Hello HRichard
IMHO I think due to the Extreme higher pressure of the Federal .327 Magnum round it would not be wise to attempt placing a sleeved barrel in a conversion of this round. Since the average SAAMI Pressure of the Federal .327 Magnum round which is over 45,000 PSI which is in Excess of the more popular .357 Magnum cartridide Pressure's I fear a huge liability would be involved in barrel sleeving for it. Bowen will punch out a .22 caliber barrel or .22 bore cylinder for this cartridge but I am not aware of any other caliber's he would use to convert this caliber change to. The sweet part is if you can locate a Model 16-4 revolver which is all ready chambered in the .32 H&R Magnum cartridge all he has to do it lengthen the cylinder throats roughly an 1/8" to make his conversion to the Federal .327 Magnum work, and I only had to pay $95.00 for that Job on mine when I had it done. I am Very Blessed to also have a Pre-16 and it is a Five screw Wide rib revolver from 1951 time span. Bowen could not convert this revolver either as it's cylinder window is far too short to make the Federal .327 Magnum cartridge work in the gun. I don't know why anyone would even think of molesting one of thse classic's in .32 S&W Long caliber any way do to their high collector value, one would have to be insane or have more money than brains to try modifing one in any way or form. Mine shoots as good as it looks and really produces some nice tight shooting groups, when I do my part right, it comes through Very well on Target... Hammerdown

Thanks, that's about what I expected, the pressure primarily. Looks like I'll keep looking for a 16-4, 6", which may be easier to find than 17 barrel & cylinder.
