So I shot my .50 cal Traditions Hawken rifle, today at 100 yds (backpack rest / hood of truck), with 85 grns of Pyrodex RS, put 5 roundballs in 5" with open sights. not great but the best I can muster out of these old eyes (optics not allowed on muzzleloaders in Washington state). so what would be the best projectile for Blacktail deer? roundball weighs 176 grns I think, and velocity should be around 1900 fps. Maxiball would be 320 grns at 1500 fps. Are these figures correct??
