I got My headpace gages and tested the Rifle I have been shooting...It flunked "harder"than Tom Selleck WAS in the magnum Years!I had to add several pieces of tape on the Field gage to stop the bolt,so it was a good thing I custom loaded each round to the chamber before I went out!

Barrel over indexed with hand tightening originally,,so I had to peen the shoulder for proper crush and according to My eye and laser level it is indexed correctly..Crap,now I have to save for another barrel :( I do not fear My reloads,I just want to be able to shoot factory loads whenever.

Any chance of getting the barrel to someone with a lathe that can take a little off the face??

credit? sure sounds to me like you were suggesting that the Magnum years were a failure

No,I was a magnum addict as a Kid.I would still watch if I could,but not on My basic cable channels...I just"mis-spoke",My comment was supposed to insinuate that Tom selleck was sexy(but not in a Gay way).

I fixed it,is that better My mildly Homo Friend?

aahhh....you were referring to Tom's hardness and not his "flunking". that is much better. Thank you for the clarification.

BTW, what's wrong with thinking of Tom Selleck in a gay way? who hasn't? If I had a nickel for every time I thought of Tom Selleck when I had my wife on all fours...

OK, common for M14 go past TDC which is why Shuff , myself and Tony G -it was actually his design-have a tool to fix that problem. No peening necessary. AFAIK, all M14 barrels are chrome lined and the chamber can't be reamed, unless some bozo did it before you got it. I would start checking elsewhere for the problem. Also keep in mind that NATO field is .007 or .008 more than SAAMI, so you may be able to shoot 7.62. Anyway, I'd check the bolt. Stu

Handloads won't make up for an un-supported case rim. Shoot 7.62 brass as it is much thicker.

Soooooooo, you might not have any problem here at all.

Okay, Gus Fisher talking now.

"For the 7.62mm: GO gage is 1.634" (the same as NO GO for the .308 Win.). NO GO is 1.638" (the same as the Field Reject for the .308 Win.). You will probably never find either spec. in military manuals, as they only list the Field Reject. The Field Reject is 1.6445". Now folks, that's a WHOPPING .0145", or 14 1/2 thousandths, over the minimum headspace for the .308 Winchester!!! To give you an idea what that means, the ENTIRE range of GO to Field Reject for the .30-06 cartridge is only .010" or TEN thousandths of an inch.
Therefore, even if you think you may have too much headspace in your rifle, you still may fall into the safety range of the 7.62mm cartridge."

And there's more . If you're using a Chinese or SAI bolt that may be your problem. Also, the bolt may have been lapped before it came to your possession. I'm done.
