33-55 cpa 44 1/2 single shot
My bud picked up this gun and it is very nicely done. It came with a 335~gr Hoch mold so that is what we're going to try. My question for the 38-55 shooters here what alloy? Think it is a 14 twist and will be using bp. Have new starline brass rcbs dies. Bobw

Bob I have a schuetzen CPA with a 38-55 1:14 twist Badger barrel. For whatever reason, they didn't chamber it with their very shallow leade reamer, but with a 6 degree one. As a result it takes a lot of effort to breech seat the Hoch 335gr tapered bullet and that one never shot that great for me. Instead I've been using the BACO 377325CT ( breech seated ) which is a tapered Creedmoor bullet. It has shot extremely well with a lot of Goex Fg I burned through.
That's for breech seated shooting though.
For fixed ammo, I have a Hoch 377310 bullet that shoots pretty decently in a C. Sharps 1885 with a 1:14 twist barrel.

Thanks guns my memory failed me on the bullet it is a hoch mould but..376 and 310 weight. The bottom 2 at 376 and the ones forward of that less smallest on top of course. What alloy do you use? Powder charge? The gun uses the 2.125 case and dropping a bullet in the chamber pushed out shows me a 2.645" oal max. This sound familiar? Bobw

I have a CPA 38-55 with a 15" twist Badger barrel. For the most part I have shot a Postel bullet that runs about 310 or so. The alloy is about 20-1 give or take some. I also have a Hoch 376-300 tapered bullet that I have shot a little. I just put it together over about 45 gr of Ctg Goex and it shot well enough to 10 out of 10 on pigs at 300 M. Now I did use the whole pig but I figure that is a pretty good start to things.

Bob, I also have the 376310. I don't like it as much as the 377310 bullet. The 376 one is tapered but the 377 isn't. I've never got better than 2 moa with the 376310, but when I shot it, I would have used 20:1 and Swiss 1.5.

I shoot the lyman 379674 and my DDPP both at 16+1. Ive also ran them with Lyman #2 with good success.

While I shoot a 38-55 am sure my 12" twist load of 52gr of 2F Swiss and BACo 365gr Creedmoor bullet hold little interest for your slower twists.
