M-305 re-barrel?

(Hmmm, I see that Hungry beat me to the punch...)

It is likely just a problem with hard brass. To rule out a chamber problem, a few things should be measured on a piece of fired brass. Neck diameter (use a pair of calipers), and fired cartridge headspace (with an RCBS precision mic, or similar tool). If you don't have those tools, mail a few pieces of fired brass to Hungry (or to me if you prefer - my rates are the same as his ;-).

Thanks for the offer.... I mailed some brass to Hungry last night :)

The rifle will be on the way to M-14 Doctor by the end of business tomorrow.... (If I can find the box it came in!)

Thanks for the advice and the help fellas!

Cheers!

Would the brass falling into the snow have have anything to do with it ?

That's a good guess but brass doesn't harden like carbon steel. In fact when you hammer brass or copper it work hardens. To get it soft, you heat it red with a torch and dip it in water. That anneals it making it soft. Carbon steel would harden if heated to critical and then water quenched.

What about getting a box of 150 grain winchester ammo and seeing if it splits the necks?

Good luck!

Ok I got the gun back from my g-smith today.... I must have missunderstood something because the chamber (head space) is only 10 thou bigger than no-go..... Pretty much, much a-do about nothing, it seems.....

Cheers!

My M14S is headspaced at 1o thou over. No big deal. Only thing is it shortens brass reloading times. Not a big deal.
