One of the best sources for most all the variations of the 03, is the book The Model 1903 Springfield Rifle and Its Variations by Poyer. As to the OP's? about shooting factory ammo or factory ammo with heavy bullets in an 03A3... it has already taken care of because the 30-06 factory ammo specs are for the lowest common denominator 30-06 rifles. No issue with the 03A3- it's plenty strong.
And yep as has been posted, it's a completely different issue with the Garand. It's all about port pressure as the bullet travels down the bore and gets to the gas port. If the pressure at the port is too high it may bend the op rod.... or worse!. Of course if it is too low it may not cycle the action. Powders with slower burn rates than 4064 or 4895 are not recommended for the Garand. The ideal round for the Garand involves both the right type of powder, powder charge and right bullet. I found 46-47 grains of 4895 under a 150 gr jacketed spire point bullet to be about ideal for a Garand. A good resource for anyone with a Garand is The M1 Garand Owner's guide by Duff.
