At about 4:00 PM CST a nice spike buck fell to my CVA Frontier Rifle, 50 caliber and a Lee 320 REAL boolit (Maxiball?) and 100 grains of Pyrodex. The shot was only 20 yards, no great feat of marksmanship, but he hit the ground and didn't move from the spot, a through and through that tore the lungs in half. Damage is impressive. I'm much more impressed with this than I was my first kill with a 44 Magnum rifle and a cast boolit, and I thought that combo was a deer slayer. This is my first deer with a muzzleloader and I must say that I'm quite impressed. I may well do some more hunting this year with the rifle, even though centerfire rifle season starts tomorrow (Saturday, I'm posting at 9pm CST on Friday). I'm definately going to have to try round ball now. Thanks for the responses to my earlier post guys, it helped a lot.
