Hello all,

I have a pre-66 110L in .308 that has been a great shooter for years. Recently the groupings went to the size of a watermelon. Low and behold, my barrel had worked loose! The barrel has a hump and iron sights, and barrel nut FYI.

Fast forward reading many posts on here, I buy a .308 headspacing set.

here is where I’m at..

go gauge in, head spacing doesn’t line up with iron sights. It’s about 90 degrees off, bolt will not shut with iron sights lined up. I back out 270 degrees to line up iron sights once again... field gauge chambers with ease.

The bolt is the old style extractor and I have not taken it apart. This might be why the go gauge won’t close on the tighter barrel position. I’ve searched extensively for a tutorial of disassembly. Any one know how?

second, knowing the iron sights were lined up previously, should I position the barrel in the tighter position, take it to the range and let it rip knowing the go gauge had an issue (possible due to extractor)?


I love the rifle as is, and would love to not rebarrel with new bolt etc.

thanks in advance!
