Magnificent and historic rifles. Truly helped win the war, and truly saved many of the "greatest generation." As alluded to above, Patton called it "the greatest battle implement ever devised."
But anyone thinking of reloading for it would be well-advised to do some research first. Its gas system is sensitive to port pressure, and requires powder in a narrow burning range to function and not damage itself. Neither is it tolerant of heavy bullets. Ignoring this can result in a bent op rod or worse.
This also limits the numbers of factory loadings which are appropriate. If you buy off the shelf only grab the stuff that specifically says it's OK for Garands (yes, it is out there). Many factory loads are optimized for bolt-actions and max performance, so utilize slow-burning powders and/or heavy bullets, which will bend a Garand op rod just as fast as an inappropriate handload.
There's a fistfight going on in another forum even as we speak about neck-sizing versus full-length for this rifle. Baffles me. Garands can absolutely fire out of battery, for several reasons, not the least of which is insufficiently-sized cases. Yeah, not supposed to, but while rare it can and has happened. Oh, and about primers...
You have a great rifle, learn its nuances and enjoy the heck out of it!
