I used 27 grains of 748 and a 70gr Speer bullet for years in

in a Mini 14 with its 1/10 twist. When I got my AR with a 1/7 twist it could not handle that load. First shot blew the primer pocket so big you could put a large rifle primer in the hole. Plus it locked up the gun requiring beating the case out with the rod that the Colt had in the buttstock. Didnt use that load again. Although it was maximum that faster twist must have raised pressures dramatically
