He was loading some 270 bullets that my uncle had previously loaded for me. The orginal load was H-4831 behind 150gr NBT with cci 200 primers my friend thinking that IMR 4831 and H 4831 were the same loaded them with the H 4831 with cci 250 primers. Well the loads have worked fine with just some minor cratering of the primer. I am about to load for this gun again and I am not sure if I want to use the excessive load this time. Has anybody loaded a 270 this hot. It is a M-70 push feed. This load is almost 3gr higher than the Hornady book says is MAX ...
