I have a blued model of Lyman's .50 cal Deerstalker that has the deeper grooves meant for PRB and 1:48" twist.

I had checked the length of the 255 grn bullets I have and they are about on the mark for a 1:48" twist using a formula adjusted for muzzleloaders that I was given.

I believe MMP is the only one who makes a .458" sabot for a .50 cal.

I've heard that soft lead projectiles don't fragment at muzzleloader velocities. I've yet to hunt with mine, but a .490" RB can easily reach 1900 fps or more.

I bought a small number of 320 grn REALs to try out. I just bought some Lee casting equipment and RB molds for my rifle and pistol. I'm looking at molds for conicals/bullets next. I like Lee's affordability.
