38 SPL +P and HS-6
I just registered to post this (been lurking for a few months)
I bought some Buffalo Bore 38+p heavy for SD loads (158gr LSWCHP) in my S&W 642 (+P) Airweight. 1-7/8" bbl.
However, after shooting these sticks of dynamite, i decided to load something close but not THAT hot. The recoil was painfull and follow-up shots would be difficult. But it chrony`d at 1024 avg.
I read some excellent data on HS-6 by ArchAngelCD for FBI replica loads.
I bought some RimRock 158gr LSWCHP and put them atop some HS-6 with CCI-550 Primers and I got 860-900 (avg 876) ft/sec.
Recoil still had some sting but was manageable.
No leading, no flash and no smoke. Primers looked good too.
only thing I noticed was a little discoloration on one side of each case?
Anyway, just want to say thanks to ArchAngelCD and others that did the load testing on this great combo.
Question: does this 40 ES sound ok? ( My cheap chronny doesn't do SD)

I'm glad HS-6 and the tests helped you out. I do like using HS-6 for FBI replica loads.

An ES of 40 is in the ball park for that load.
It really depends a LOT on the different types of powders used
to get that high of a fps out of that load. I have had some
powers at that speed with a ES of 26 to a high of 123 but this
does not mean that either is not accurate.
I had a fast power at just 15 ES and it was all over the place.
In my steel J frame I have two loads that average 851 and 861
velocity but my most accurate load in this weapon is at only 822
fps that will group and shoot at the same spot every time I shoot it.
Some J frames with the factory FBI ammo only clock 800 fps
which leads to.......... do you really need the extra fps in a load?

The RimRocks are gas checked so I figured I could treat them like jacketed, Do I need +850?
No, I guess I don't, but its nice to know that it can and now I can try for accuracy. What I did was strictly chrono. I have yet to see what it does on paper. Hope to try some this weekend. I may find that a little slower is much more accurate.
Thanks for the reply

By chance did you do the finger nail test on those Rimrock bullets?
Just wondering how "Dead soft" the lead was..........( Swaged )
or if they were around the 15-18 hardness of the cast lead bullets.
Good shooting.

I spoke to the owner of Rim Rock Bullets about a year ago before I ordered a bunch of the bullets. He told me the 158 gr. LSWCHP-GC they sell to the public is exactly the same bullet as they provide to Buffalo Bore for their +P loading. He told me Rim Rock uses a 30 to 1 mixture of lead to tin (which makes it 97% lead and 3% tin). That mixture appears in an old Lyman manual I have as a recognized mixture and makes about as soft an alloy as one can cast, short of pure lead.
I load mine over 8.0 gr. HS-6 and a mag primer in a Winchester Nickeled 38 Special +P case to duplicate the Buffalo Bore +P load. Found that load on this forum.

You should put a warning on that load! Anything over 7.2gr HS-6 under a 158gr LSWC bullet in a .38 Special case is over the SAAMI pressure limits for a .38 Special +P load. I use 7.0gr HS-6 and some reloaders consider that too hot. The safe charge is even less if you go by current load data. A charge of 8.0gr is into the pressures of a .357 Magnum and should not be shot in a .38 Special revolver.

Yes, and they are very soft. Designed to expand at snub-nose velocities. Will this be a problem at 800-900 fps. I wouldn't think so, but I may be wrong.

I agree, 7.0gr is plenty hot enough, at least in my Airweight it is. Your brass has to be flowing in that chamber.
8.0gr might be BB power but no way would I try that in a scadium J frame.
Besides, .... that buffalo bore felt like trying to stop a baseball bat swung by a grown man with your palm.

I disagree, it may be Buffalo Bore velocity but not power. You may need 8.0gr HS-6 to match the velocity BB is generating but they are not using HS-6, they are using a blended powder that is supposedly within the SAAMI pressure limits. I'm 100% sure a charge of 8.0gr HS-6 in a .38 Special case is well over the SAAMI limits of 20,000 PSI. In reality I have my doubts about 7.2gr HS-6.

Actually, I was agreeing with you that 8.0 is way too hot for .38spl+p and indeed should include a warning sticker. But anyway...I digress..

Ok, I have been wondering about this for a while now. Using HS-6, with 158 grain swc. At what point should a mag primer either be used or not used? I am not looking for a nuclear bomb here, just a safe and accurate load. Thanks!!

Accuracy trumps ES, you didn't mention group size . If you can hit with that load don't worry about ES.

HS-6 is an older and slower ball powder and IMO you should always use a magnum primer when loading with it. A magnum primer will insure a more complete burn of the powder and a more even burn. Any time you can make things more uniform it has to help with accuracy.
Like I have said A LOT on this and other forums, a magnum primer will burn a little hotter and a little longer but it will not create a nuclear explosion. For some reason the word "magnum" scares some people but in reality a magnum is just a bigger bottle of champagne. For example, Winchester's LPP are rated for both standard and magnum use but nowhere in the industry is there a warning to reduce the powder charge when using a WLPP. If there were any chance at all of going over pressure with a magnum primer there would be warnings all over everything, especially in our litigious society.

From my HS-6 Testing in 38 Special, I got the following:
38 Special - Hornady 125 XTP - CCI 500 1.450"
___________________________________________________
Powder Chrg. Avg. Hi Low E.S. S.D. Est. CUP
HS-6 7.0 943 956 929 27 14 15,327
HS-6 7.5 1030 1038 1022 16 8 17,841
HS-6 8.0 1119 1123 1115 8 4 20,675
38 Special - Speer 135 GDHP - CCI 500 1.460"
___________________________________________________
Powder Chrg. Avg. Hi Low E.S. S.D. Est. CUP
HS-6 6.5 885 909 851 58 31 14,866
HS-6 7.0 959 963 956 7 6 18,300
HS-6 7.5 1024 1057 1005 52 29 22,412
38 Special - Magma 158 SWC - CCI 500 1.460"
___________________________________________________
Powder Chrg. Avg. Hi Low E.S. S.D. Est. CUP
HS-6 6.0 848 853 840 13 7 14,934
HS-6 6.5 938 957 922 35 24 17,115
HS-6 7.0 988 1005 960 45 24 19,498
Note these are measured from a 4" 686 so I think the numbers are real representations of what HS-6 does. Also, the pressures listed are only guesses based on calculations from Hodgdon's published data. They are NOT measured pressure results.
Hope this helps,

I did go up to 7.5 grs with the 158 cast which yielded an avg velocity of 1085 fps, but I would only shoot that in 357 mag chambered guns. It was accurate, but not really 38 special anymore, really getting more into 357 Magnum level.

Mark, the only change I would recommend is the use of a CCI-550 primer instead of a CCI-500 primer. My FBI Replica load matches your 7.0gr HS-6 load under a 158gr LSWC bullet but with a Magnum primer.

That load might be ok. It might not be ok. How much money do you have in the bullets? How much would it cost for a new gun if it blew up? I would not shoot them simply for my peace of mind. It is your call.

Airweight?????
And a Hound Dawg Howdy to you from SC!
Don't push that air weight too much too often. It'll take a few defensive loads when needed but not a steady diet.
Pachmehrs or Hogues help, but they make the grip more bulky.
I can shoot my model 38 in stock form but I don't want to! Even target loads smack a little.

Before you try some of the loads shown here, you might compare the data with loads from a reputable handloading manual.

Keep in mind the ES can be skewed (and resultant pressure) by the length of the brass, which affects the crimp. If all is not consistent the ES will vary sometimes a lot. I also recommend you obtain a current reloading manual, and keep within the guidelines.

My post is for anyone shooting +P in an " air weight " 38 spl . After about 1000 rounds of +P , mine required a trip back to S&W as it was just too loose to continue shooting . I recommend using the +P sparingly and shoot std 38spl most of the time . YMMV Regards, Paul

Was that a recent manufacture gun? I may have to baby my 637 a bit more.

You brought back a 4 year old thread to talk down to others here? No one forces anyone to shoot data posted on a forum. I personally shoot the 7.0gr HS-6 load and I do have published data to 7.2gr. No need to buy anyone a gun, just don't shoot what you don't like but don't talk at others either.

It happened to my S&W 642 that I bought about 10 yrs ago . I called the factory , told them it wasn't a problem with manufacturing or assembly , that I simply shot it an enormous amount and it needed servicing . I had got it through " Davidson's " ( gallery of guns ) so it was covered for repair . Regards, Paul

+1. I also shoot the 7.0gr HS-6 load. It's the ultimate +P load.

Wow! 4 years old or not, there is lots of great advice here!
I notice that Winchester Small Pistol primers come in two flavors...WSP and WSPM. Sooo...saying I use Unique, AA#5, Universal, or HS-6. for mid-range/FBI equivalent loads @~ 900-1000 fps, is it permissible to use Magnum primers with all of them, to reduce inventory/chance of a visit from Mr. Murphy?
Would backing the load off .2-.3 gr. for the magnum primers be advisable, or, because these are not full snort loads, just use the original load, and interchange magnum/standard primers, according to availability?
Thanx

I have been using CCI #550 magnum primers in my .38 loads and find they work very well with HS6 with both 125XTPS and 158XTPs. Have not quite worked up to +P loads with them yet, but they seem quite manageable. I also have 5k of #500 small pistol primers, so I am sure that I will load up a hundred or so and see just how much, if any, difference the two primers show...
Don't really expect much difference from what I have read, but who knows...

This thread is going to drive me to buy HS-6.
What HS-6 loads do y'all use for 44 Mag?
Anybody use it in .32 Long?

Would backing the load off .2-.3 gr. for the magnum primers be advisable, or, because these are not full snort loads, just use the original load, and interchange magnum/standard primers, according to availability?
Thanx

While magnum primers can be used some powders actually perform better with a standard primer. Unique and 2400 are good examples. If possible use magnum primers for slow ball powders like HS-6, HS-7, W296/H110 and the like.
Side note, over the years I have loaded many hundreds, maybe a thousand of the HS-6 FBI load and I think I will never change.

I have a theory, (well, actually, I guess it would be more accurate to call it a hypothesis) that using a magnum primer might help with position sensitivity. Anybody have any thoughts on that?

HS-6 in 44 mag , 240 gr bullet: 13.0 grs
41 mag , 210 gr bullet : 11.0 grs
357 mag , 158 gr bullet : 9.0 grs
38 spl , 158 gr bullet : 7.0 grs
I use a full magnum primer . I get my best accuracy with these loads and I consider them close to max .

While as you have found HS6 works, its not a very good choice for your 1 7/8 barrel. I bet you could easily dupicate that velocity with a faster powder like 231, tightgroup, Bullseye, and get aound double the loadings per lb. Probably generate even less recoil and muzzle blast.

I have to disagree. Unlike rifle barrels powder speed has very little effect in handgun cartridges. The powder that delivers the highest velocity in a 4" barrel will also do so in a 2" barrel.
Additional, the faster powders will reach pressure limits well before you generate the desired velocity. The slower powders will get you there within limits. Of course you don't want to use the slowest powders but the medium slow powders like HS-6, AA#5 and others will do a good job.

Hes not trying to build the fastest speed, He's trying for a lower speed, lower recoil.
Using the fastest powder that can generate the desired velocity while staying within pressure limits, will result in less powder used, less recoil, a cleaner gun and usually lower SD.
ANd you are dead wrong about burn rate having no effect. thousands of USPSA shooters would disagree.
I can load 124 grain 9mm's at the same velocity as WWB 115's and my loads generate noticeable less and a flatter recoil. Simply because I use one of the faster powders that can get the job done, While I am sure Winchester, uses a "medium" powder that can work in many rounds due to economy and the fact lots of uninformed people equate recoil with power.
