This is just me speaking but I have been shooting and hunting with Winchester 150 grain PowerPoint .30/06 factory loads for better than twenty years through several Garand rifles with no problems whatsoever.
That is POWERPOINT NOT SILVERTIP ammo which is loaded differently.
I also shoot Winchester Black box 168 grain .30/06 Match ammunition with no problems in an M1 Match rifle.
If you are familiar with reloading, a safe practice to formulate hunting ammunition for the M1 rifle is to pull the bullets from surplus FMJ military ammunition and replace with commercial 150 grain softpoint bullets.
A press mounted collet type bullet puller such as the Forster is best for this practice.
I am personally not a fan of adjustable gas cylinder locking screws.
