These abominations were done by Importers in the late 1960s to clear out remaining stocks of good M1909 Argy Long rifles and Carbines(some Mint), due to GCA68 and an Argy ammo shortage They simply ran a standard 30/06 reamer in, and extended the chamber. Nothing was done to the rifled part of the barrel. So a standard .30/06 cartridge will fit, and fire...the bullet, being grossly undersized, with rattle down the bore (usu.. .314) and go on its inaccurate way, occasionally keyholing. The Only solution to your situation (given that the rifle is already a "sporter") is use the action as the basis for a new Sporting rifle. Ie, get a new barrel, [properly made for 30/06 or 308]. If you had a still compelete Military rifle, the shootable solution would be to handload your own .30/06, using .312 (ex .303 British) projectiles, and Polishing out the Neck area to allow for the increased neck diameter resulting from the use of bigger diameter bullets. Otherwise, "neck Crowding" can occur on firing, raising Pressures dramatically. Regards, Doc AV AV Ballistics.

Land diameter vs. Groove Diameter... Here's a diagram, I stole from Parashooter: Military Mausers had much thicker lands than typical US-made Military rifles. Doing the M-Garand "bullet test" on a 7.65 Argentine bore is comparing apples to oranges.

It may surpise you, or it may suck. If your a handloader you could load your .30-'06 brass with .311/.312 British Enfield bullets. Slug your bore first to make sure this would be an appropriate diameter bullet and that these bullets will slip into the neck of your fired brass without resistance to insure the chamber neck is not to tight for these oversized bullets.

Best to slug and mike the bore and get a chamber cast. Only real problem with using the .312 bullets would come if the chamber neck was too tight. Thats not generally a problem if the chamber was cut to military specs.
