It says "Safe for use in: All M1 Garands and 1917s" right on the box.Are people shooting this 167 grain .30-06 Creedmore out of a M1 without an adjustable plug? I've always stuck to the 150 grain milspec loading myself.
My reloads for M1 have all been 168gr except for 20 using 150 that I made up last week to compare to the 168s (haven't tried them out yet). I'm sure others will chime in but most people I know use 168 for the most part, but some do use 150. I got into reloading a few years back specifically for my M1s and I remember asking around and most people told me 168 was their preference, so that's what I've rolled with. I've done 150s with my 1917, though.
My manual has M1 specific loads (as well as 7.62x51 service rifle) loads, I follow those.
