Buy a chronograph, a prochrono digital is around $100. It'll tell you right off the bat if you're too heavy on the charge weight. I won't fire the first round through a new barrel without the chronograph out, it's a waste of components in my opinion.
I'll know if I'm heavy on the charge at what velocity?
My references list max V anywhere from 2976 fps to 3047....
shopping for chrono, next on the list, Like tonight.
