.............Help me get a handle on this. I understand the issues with the gas system of the Garand. Port is close to the muzzle, the op rod is long (with a couple slight bends) so is 'Flexy (flexie?) and much easier to have issues. On the other side with the M1A, the gas port is MUCH closer to the chamber (subject to higher pressure) but there isn't much of an op rod to bend.
So I suspect that the M1A is much more robust as regards pressure, is the M1A suitable for use with most any factory loaded ammo? Would there be a restriction on bullet weight in said ammo? I just got a Springfield Armory 'stainless loaded' model M1A, and just want to check what knowledgeable users might have to say.
