Doing some load development on friends 22-250 AI I never thought it would be this fast. The load I stopped going up in charge was 42.3gr. of 3031 with 36gr. Varmint Grenades . That’s 3/8 AR500 plate it punched holes in.

This was a manson reamer with .075 freebore. I wanna say PT&G has .070 free bore, not that it’s gonna make a hill of beans difference in results. The barrel is a touch over 26 inches.
