If we are truly talking about developing a load for a child/woman or recoil sensitive person, I'd think starting at the 70-80g level would be more appropriate. My wife won't shoot anything over 80 grains with a 200g bullet. Yeah it's a lighter bullet but that's still a good amount of powder. Even with roundballs most kids won't want to shoot 100 grains.

Just a thought... I'm interested in the results at any level.
