Re: problem with M1 garand
In training we were issued Lubriplate grease for our M1's. I still use it (or White Lithium Grease) for my personal Garand. We were instructed to find the sniny wear points and finger swipe a very light coat of grease to cover them.
Look up Scott Duff's <span style="font-style: italic">Garand User Manual</span> for a better insight into the rifle.
My handloads are commercial (I use Rem ) brass, Win WLR primers, and 50.0gr of IMR-4064 with 150/155gr bullets, and 47.0gr of IMR-4064 and 168/175gr bullets.
Make sure the primers sit flush or lower, don't feed/fire any that protrude. No need to manhandle the primer seater, just make sure they're fully seated.
I would strongly advise against hand chambering single rounds and releasing the bolt to fly home free. All rounds should be fed from a clip. The clip feed design prevents the bolt from exceeding a safe speed, and is intended to prevent slam-fires.
A lot of folks blame non-military primers for slamfires, but I personally think the problem stems from incorrect loading/feeding practices. Military primers are made more durable/insensitive because (in my opinion) the military understands that some buck privates are going to ignore the safety lecture. The cost overhead for these military primers is paid in reduced accuracy.
For single feeding, find a
SLED (Single Loading Enhancement Device, essentially a modified clip that allows clip feeding and remains inside the receiver when the bolt locks open), and your shooting will be a lot more safe and convenient.
