I thought some of you might enjoy this. This past summer, a friend gave me a set of forming dies and reloading dies for a .38-45 Clerke. They had belonged to his late stepfather (an avid Bullseye shooter back in the day.)

The round is a .45 ACP necked down to .38 caliber. As originally conceived, it was meant as an inexpensive way to get a .38 centerfire gun for NRA Bullseye. The newly introduced Smith Model 52 was pricey, as were .38 Special conversions of the old Government model. Bo Clerke dreamed this up in 1963. Basically you only needed a rechambered .38 Super barrel, a bushing, and a lighter recoil spring. Nothing else needed to be changed on a Govt. Model, since the back end of the case was still a .45 ACP. The slide (extractor placement) and magazines all stayed the same. You loaded it with light .38 Special data.

Here are three sample rounds, one each with a 158 SWC, a 147 FP, and a 124 TC. These were just molds I had available.

Here are the five steps to forming a case. The forming dies are a 4 die set, and the 5th step is to just run the case into the .38-45 resizing die.

Here is my Bullseye gun (shown here set up as a .45ACP). It was fully accurized (as a .45) buy Jack Best back in the late 80s. It is exceptionally acccurate, I have the obligitory 50 yard Ransom Rest target he fired, showing sub 2 inches with Federal Match SWCs. I can't shoot anywhere near that well, but its nice to know the gun can. The target shown is what I can do at 25 yards (again as a standard .45)

And finally, here is one of the many 50 foot bench targets I shot this winter.

Our indoor range is 50 feet, I am looking forward to seeing what she will do at the longer ranges outdoors once Spring hits.

While I realize that nowadays, it would be far easier to just shoot one of the fitted, super accurate 9mm 1911s that abound, that wasn't the point. I love to tinker, and the historical ramifications of this intriguing round made it irresistible to me.
 
The number of cartridges that gun fanciers come up with never ceases to amaze me. And folks say the stars and the universe are limitless. I think wildcatters could give the universe a run for it’s money! Just when I think I have heard of them all, I read something like this. Absolutely fascinating and man what results you have obtained. Thank you for posting.
 
I bought a set of dies such as yours at a gun show for 25 bucks. Actually loaded a few rounds just as an exercise in making them. Think I made about 20 or so......looked good but I didn't have a barrel to fit to a gun...so I sold them...on ebay I think. A couple years later I found a barrel set up...but didn't buy it at that point. It was a bit of work to make the rounds. And I was not a bullseye shooter anyway. Had enough wildcat rifle rounds to load for. Still it looks like you have had some fun. Good shooting. Nice pics too
 
Yeah, I agree. I had an early dismissal yesterday, so I spent my afternoon forming cases. 100 cases equals 500 pulls of the press handle, then trimming and deburring!

Still, only need to do that once! It was fun!
 
I've been aware of the 38-45 since the '60s, but didn't know the steps involved in case forming. Thanks for posting this.

BTW, some years ago Casull took the concept and ran with it in creating the 38 Casull. Stronger case head required, but otherwise looked just like a 38-45 to me. A friend bought a new 38 Casull pistol and some factory ammo. Averaged 1760 FPS with a 124 grain bullet when we chronographed it. Apparently not what Mr. Clerke originally had in mind at all;)
 
I've always wanted to make up a nice 38 Super on a 1911. Never have attempted it. Other than a bbl(which I have) what would I need to shoot 38 Sup out of my 1911 99 Range Officer? I've never even shot that in 9mm so got to break it out one day. Is it hard to change a 9mm, to 38 super? Wow..another round to load for of I can convert it
 
Wow, have not seen one of those in many years. I have been reading gun magazines for 50 years or so and remember reading a lot about that cartridge.

I also remember the Casull version.
 
I remember reading about that cartridge in various reloading books/magazines in the early 1980's. Always thought it'd be a good way to crank out hi-velocity 158 gr. semi-auto rounds in a 1911 formate. Imagine that if one used USGI 7.62 brass to make the cases, velocity could with proper springs be impressive. JMHO. Sincerely. bruce.
 
Bruce,

Yes, back in the 80s some guys took just that approach, namely to try to hot rod the round into a quasi .357 magnum. Among those was my all-time favorite gun writer, Dean Grennel.

My interest is strictly the original goal, a mild shooting .38 bullseye gun.

Thanks for all the replies!
 
I like it, but then I like unusual calibers.

I recently built an AR upper in 6mm Mongoose, a shortened .223 case with the should pushed back slightly and converted to 40 degrees and necked up to 6mm. Just finished fire forming about 100 cases and starting load work ups.

I also made some .30 Herrett rounds once. Great pistol round. That gun was, unfortunately, stolen.
 
Hey, nice write-up.
Did you post this on the castboolits forum? There is a recent thread there.
It was a great innovation. The original intent was wonderful. Some folks muddied the waters by reimagining it as a hi-velocity vehicle. I bet there were more than a few mishaps!

I used to shoot 2700 matches with Dave Salyer, a great shooter and gunsmith. He experimented with 30 Luger as a bullseye CF cartridge in converted 9mm and 38 Super 1911s. Worked very well, especially for low recoil and 50 yd accuracy. He wasn't able to get Bar-Sto to make the barrels.

I’ve always wanted to try that. Where did he get a .30 Luger 1911 barrel? - make it himself?

To the OP, thanks for starting the thread. Like others, I had heard of the .38-45 a long time ago but did not know what the case-forming procedure was. Doesn’t look too bad. I’m curious about your 147 grain bullet. It looks promising. Who made the mold?

I am looking at adapting an ATI FX9 to shoot 38Super. In my research, I have found that I only need to swap out the barrel, bushing, and magazines. I also found that I may have to adjust the ejector.
 
6String, yes that was me over on Castboolits. I use the same screen name there as well.

M29, sadly these were some commercial cast boolits I had laying around, so I don't know whose mold it is. I guess I was misleading in the original post. I cast the other two, but not the 147s.
 
Back when II found the dies I was under the impression the cartidge was supposed to be a kinda semi auto 357 mag...like a fore runner of the 357 Sig. Glad to find out the real reason for it. Learn something new every day on the S&W site. Thanks for the history of the catridge
 
Skeet 028,

I'm intrigued by your screen name. Are you a skeet shooter that favors the 28 gauge?

I am a skeet shooter...favoring the 28 ga?? Before I ever broke a 100 straight with the 28 ga I had 21 99s(not in a row) missing low 6 on doubles last round 9 times. I happened to be shooting with one of the best of all times(Wayne Mayes). Last round before I shot station 6 I gave him a 28 ga shell and told him if I missed any target on station 6 to just shoot me to put me out of my misery. He said matter of factly...OK! Kinda believed he meant it so I didn't miss. .Broke a 100 straight in the next 5 shoots. 28 was the only state championship I never won in Maryland. I actually prefer the 410...no recoil! yippee

Back to Bo Clerke...didn't he get into some other stuff...like a line of guns or something? I think I met him at either a NASGW or Shot Show many years ago. But I am much older now so have a bit of CRS.
