Re: WWII Vintage .30-06
If it's an A3-03 Springfield, which was the WW2 issue in the early part of the war, using the same ammo will be fine given the rifle is in good order. I use the same hand loads in mine that I use in my modern rifles with no issues and fine accuracy. If it were a Garand, this would not be the case as cartridge pressure and therefore load recipe plays a role in proper function.
