M1 Garand barrel

lightning2923
On gauging the M1 grand barrel what is the ME and what is the TE? What should they be on a good barrel? Mine needs to be replaced. I don't know what it has been used for but thr rifling does not come to the end of the barrel.

    I have a Springfield Armory M1 Garand. Its wood is in perfect shape, and the receiver and action look good. The barrel is shot, though, and I've been told that it needs to be replaced.
    Is this barrel a viable replacement, or is there another source for M1 Garand barrels?

    Thanx

    Here's the link to the barrel I'm considering:

    If there is no rifling at the end of the barrel you got a shoot out barrel or someone over did it with a cleaning rod. There is a way to ream the barrel back and use the rifling down in the barrel to support the round when leaving the barrel. I have seem some good shooting M1 rifles with the barrel reamed. The readings are 0 being no wear to about to 4 or above ok for a shooter.

    If you have a single round of USGI M2 ball, you can use it as a "poor man's" Muzzle Wear gauge. Insert it in the front of the barrel point first, & measure how much copper jacket remains. If 5/16", it's almost new; 1/4", excellent; 1/8", it should be good for hunting & informal targets; little or nothing showing, not real good; case enters bore, replace the barrel.

    You need a gauge to measure Throat Erosion, but barrels with excessive TE often continue to shoot well.

    Sadly, the supply of new USGI barrels is nonexistent. Most used barrels you see offered were taken off for a good reason. There are some decent commercial barrels available from CMP, but they aren't as good as USGI.

    Hello Lightning: In my experience / observation, nearly all muzzle erosion comes from careless cleaning; with a "field" sectioned cleaning rod and a ham-handed approach to cleaning. Throat erosion comes almost entirely from shooting. The old geezer that built my first Garand for me advised that the barrel was good for "about 40 lbs of powder". He was talking match shooting and the "tell" on the range is when it stops shooting predictably (as in hay! where did that 7 come from? I called that a 10!?) Most guns with a lot of throat erosion and little muzzle wear will still hold the 10 ring at 200 but go sharply down hill at 300 and 600. A gun with very much muzzle wear will generally not group well starting at 200. With respect, I do not agree with the comment about the new barrels from the CMP. I am personally aware of 6 Garands with new CMP barrels in the past three years and they all hold the X ring at 200 in our state and regional Garand matches. Great barrels at a good price.

    HEY! Thanks to everyone the info. explanes a lot. Even though the barrel is pretty much gone at the end it still puts all eight rounds in a coke can size hole at 50yrds. About as far as I can see with my eyes.

    This rifle was built to shot between 200-500 yards, I would almost bet that that group will open up to not hitting the target at 300. The point is what do you want to do with the rifle, If you are going to shoot a fifty yards you are going to be happy with the group.

    HEY! it's just a shooter for me but I do like to hit what I shoot at. I do have another barrel comming that is right at 4 and 2 I just need to find someone here around the Birmingham, Al. area who is good with the M1 and can replace the barrel for me. I could do but at this time I can't afford to buy the tools I need to take the front stock apart or the barrel vise for the grand.
