I have a serious itch to buy an M-1 Carbine and I really do not know why, perhaps it is the nostalgia of the rifle. Anyway, I would like to know if there is a way to tell if the barrel is shot out without useing gauges (which I do not have). I know you can get a good idea by using a bullet with the M-1 Garand. Can the same concept be applied to the Carbine? Thanks

    How do you gauge an M-1 Barrel without a gauge? I have read to use a bullet, but exactly how far in or what exactly am I looking for it to do to tell how it measures? Thanks for any help

    Thats the way I use. It will work for 7.62x54r, .303, 7.65 etc.
    Pull a .30 bullet and carry it in your pocket, hard for anyone to
    get upset over that.

    You don't have to make any excuse for wanting to buy a 30 US Carbine
    even if you have to change a barrel on one.
    They are great weapons and with the proper bullets should be effective enough inside 100 yards.
    Buy a new slide spring and get those rubber magazine covers as magazine feed lips are liable to get damaged and cause feeding problems.
    With a scope,you'd be amazed how accurate they can be.

    You CAN get a quick check on muzzle wear with a bullet (not a cartridge, a bullet). Unlike the Garand and the M-N, and SMLEs, with the exception of a very little bit of Chinese made ammo, there was never a corrosive primed round for the carbine (due to non-operator serviceable gas piston) Do not often find a carbine with a bad barrel.

    Jesse: use a 30 cal carbine bullet as a gauge to check the muzzle, but be advised that many were counterbored by the military to salvage damaged ones. If the muzzle is decent and the rifling/chamber look o.k. I would just shoot it. These carbines aren't match rifles, they are carbines and usually shoot pretty good even with some wear. I recently for a carbine at a flea market (no kidding). Most of the metal was painted black and the wood was a mess, covered with Korean rack numbers. But it was made by quality Hardware (a good maker) so I bought it. The muzzle was loose and the bore shows much use; I got a new GI replacement barrel thinking that I would have to rebarrel. I shot the carbine as-is and despite the worn bore, it shoots about as well as my almost new Winchester M1 carbine with perfect bore.

    "many were counterbored by the military to salvage damaged ones. ".......just to note; NO barrels were counterbored by the 'military'........shady scrap dealers, yes

    i thought for a carbine,you use a 30.06 for the gauge...

    It is a 3006 and you look at the area from the mouth of the cartridge to the point were the bullet stops in the bore. Its one quarter inch is 0-1 and as the area become less as the bullet drops down into the barrel the more shot out it is.

    for what it's worth, when i was shopping for my garand and paratrooper carbines i was told that 1/8" or better at the muzzle was acceptable. any less was shot out.
    wouldn't be the worst thing to buy one with a shot out barrel. CMP has new barrels for $150 (last i checked).

    I have put two of the after market barrels on carbines and both shot so far to the right I would have had to remove the rear sight and stake it again in a radical position to be able to get the rifle on target. If anyone needs a couple tomato stakes I have them! Buy a US GI barrel!

    one thing you dont do is use a 30.06 bullet as a gauge. its not the same diameter as the .30 carbine! use a lake city shell, the ones it was designed for.
