I'm going to hunt with a flintlock next muzzleloader season. Traditions manuals say that the rifle will shoot most accurate with a 50-70 grains of powder, but I'm worried that I will not get the velocity to make an effective shot on a deer. I'd like to use 100 grains. Will this really make my shot less accurate? I don't have the rifle yet, but I will have it soon. I just wondered what some of your thoughts were.
