When I started reloading for my carbine, I started low on the velocity scale compared to mil spec ammo after reading that some carbine bolts will crack where the locking lugs join the bolt body ( I think mostly in the M2 actions but also in early manuf. M1's, mine is a very early, first ser # block 42')
I started low enough that the action wouldn't cycle fully at firing then increased a grain at a time until I reached a threshold that works the action reliably every time. Been awhile since I done this but think I am at around 1750 fps, I think about 200 fps under mil spec but it reliably works my action without stressing the bolt. I have some 44' factory mil ammo that I have fired in the gun and there is a definite, noticeable difference in energy between them and my hand loads.
