Well, I received a 40/65 Pedersoli in the mail yesterday, and put some ammo together to goo see how it does.
I was using IMR4227 , and although I have used it in my Shuetzen rifle and in my Snider a bit, I have never used it in a tight fitting bullet case combination.
I have shot a few black powder cartridge guns in the past - 38/55,40/65 , 45/70/,45/110 etc, , but never used paper patched bullets.
I found out this morning , even with new brass, that using the bullets made from the mold that came with the rifle, that a charge of real black powder tended to help keep the bullet stable as it was seated - that's my story and I'm stickin' to it anyway! LOL
These were done up this morning.
I also had some greaser bullets cast with a mold that also came with the rifle, but prefer to use the PP bullets as it is very easy to make the patches and apply the, with the help of posts of many of the members here that I read!
