I finally purchased my first M1 a few weeks ago after many years of wanting and was shocked at the price of ammunition. I have been reloading pistol for some time now and was considering reloading .30-06 as well. Now the questions: I have been reading that these rifles should use only military surplus ammunition due to the possibility of a slam fire, if this is true, can't you just find a harder primer? Who makes a harder primer if there is such a thing. Where would I find reloading data to simulate a military .30-06 round so the rifle will function as designed? Any input would be appreciated.
