Got myself a 35 Whelen , Remington 725, Medium weight replacement barrel. 24 inches long.1 in 16 twist.I picked up some once fired cases. I have two bullets that I cast earlier 205 grain 358315 and I have some 247 grain 358318. I'm waiting on dies . So what do you think would work best in the Old gun? I have most any powder on the bench. I plan on some paper punching and a little deer hunting this fall. For me this is a little different. I think it should be fun.
