One more thing I'll touch on here and it is related. I know it's your gun but, I don't advise using any ammunition in your Garand that isn't designated for use in a Garand. The problem with M1s is not chamber-pressure, it's port-pressure at the Gas-Cylinder. Garands run on a very narrow pressure-curve, 4 to 6000psi at the port. Most of the standard 30-06 Deerloads run upwards of 55,0000-57,000psi at the chamber which translates to about 8,000psi at the port. While not the overpressure in the Vid., this amount will end up damaging your rifle. Mainly through premature wear of the Op-Rod Tab and the bolt lugs and receses. The more pressure at the port the faster the gun cycles. Too much Bolt-speed and things get bent.
I have yet to see 308. ammo designated for use in a Garand, several man. do for the 06.
Be careful.
