Actually I have and I plan on using exactly 10% less than listed max which is 42.2 gr with a 100 gr bullet. In theory that would produce ~2900 fps with a 24' barrel but since I am cutting 3" off the barrel and adding a brake to further reduce the recoil I figure on losing ~50 fps per inch and I am at the 2750-2800 that I stated in a earlier comment maybe it will be a little faster than that but I doubt it but either way I feel since it is a listed load in the manual it should be safe. I also plan on giving it a .050" jump to the rifling to start which shouldn't increase pressure any and is also what is recommended as the starting point. For a group of people that I have never meet in person I must come off as a pretty sorry individual and lousy father if you think that I would load anything other than a known listed load for my daughter. If I want to experiment with my eyes and fingers that would be one thing but as a father I would never endanger my children.
