M2 is pretty short but there is a lot of factory ammo that still cycles fine in garands. PRVI makes a lot of ammo that other companies have either given up on or just do not want to get invested in like 8mm mannlicher or 6.5 carcano. it's pretty tough to get your hands on but to my knowledge most of it is reloadable so it's a good thing to have around when you just want to stockpile brass.
ignore my complete lack of capitalization. I still have no problem correcting your grammar.
