I found the .490 with a .015-020 patch worked the best. I purchase cotton pillow tick at Wal Mart. Its .018 thick and all cotton. I make a moose milk lube and it works real good with patched roundball.
If you have close shots, like 50 and under and want to shoot a conical, try a REAL conical. You cast them yourself. Smear some bore butter around them. And put 70 grains of powder under them. They really knock the snot out of a deer.
