I'm not looking for reduced loads. I want to see if a little faster burning powder would increase the velocity lost from a radically shorter barrel...without being SO much faster that it turns the chamber into a hand grenade.
You can't make a silk purse out of a sow's ear, & the amount that you can compensate for a short barrel with powder is pretty limited.....................
But have at & knock yourself out testing & re-testing if that's your gig.
