That or get the Schuster adjustable gas nut and set it for your particular non-M2 Ball ammo.
Shooting a stock Garand (no Schuster nut) with just any ammo could, and very well may, damage you Garand.
They require a narrow range of powder burn rates and select bullets to match the burn rate of that powder. Combinations outside of the specified range can cause an over pressure condition which will be hard on the op-rod and gas system.
I say shoot the M2 stuff.
