boats I actually have spent time using the other CPA rifle with a 30" barrel in 32-40 working with black powder loads, started with Goex 3f BP just seeing how accurate it was, accuracy was just OK, but boy was the barrel dirty, looked like I was making charcoal in it, ended up with Swiss 2f and a 225gr tapered bullet seated way out, throat is cut by CPA for breech seating and has a long lead. The really bad fouling went away and rifle shot almost as well with BP as with its preferred smokeless load using that bullet, had to use a wet then a dry patch after every shot to keep it in the black shooting off the bench. My range has a practice day before our mid-range matches and in the spring will get a zero with the rifle I will use for the match 40-70SS, but then I will shoot some 32-40's at  600yd targets. I recently purchased  a tapered 235gr .323 custom cut Hoch mould that casts a bullet that looks suspiciously like the 40 caliber Snover bullet I use, it shoots very well breech seated but did not fare as well fixed, need to chronograph both bullets so I can have a idea of drop way out there. I did ask at the last match about shooting a 32-40 in the mid-range practice and they did not have a problem trying it at those distances, speaking of low recoil 32-40 would be it.
It will be interesting to see how it does in the wind. If it shoots well enough I may have Mr. Brooks cut me a 240gr+ 32 caliber bullet on his Super Snover design, if he will it should be short enough with the round nose to stabilize in the 1:14 twist Badger barrel. No good for BPCS no enough mass, but just might work in mid-range.
Just too many fun projects and not enough time, Mike
