    Needs to visit a gunsmith for some chamber checking.

    Factory ammo should operate in this like a machine gun.
    "...But they would never find anything to beat the old Springfield ...the long sleek streamline, very slim but with potent bulges, all in the just exactly right places to give it that pugnaciously forward-leaning, eager look that marked the Springfield. Beside it, the M1 looked like a fat old man puffing with a lack of training...the two most beautiful things made in America were the ax-handle and the clipper ship? ...they should have added one more thing: The Springfield '03 rifle..."

    I love shooting my M70. I have spent most of my time shooting it off the floor. It's not a prone friendly stock for sure. haha I need a lot of work shooting it prone. But, I guess the journey is half the fun?
    Off the bench it shoots really well, so it's on me Oh well I guess I need to shoot it more!
    They are good looking rifles, aren't they?

      Why can’t the builder correct the issue?

        Very good question.

        I sent my ammo reloads that have functioned fine in my Garand/03s to chamber to.

        He cut the "Match" chamber and told me my reloads wont chamber.

        Okay I can readily believe Im a retarded reloader and seeing as my Garands/03s are over 75 years old perhaps "Match" chamber and "Springfield Armory" chamber are that different.

        Got it at home it shoots Federal 150 grain hunting ammo fine - chambers, fires, extracts.

        It wouldnt shoot Garand safe CMP sourced Creedmoor Match ammo. Well it chambers and fires but initially I had to almost beat the bolt handle in order to get the brass to extract.

        Sent it back. He said he opened the chamber some. Was leery of opening it any more.

        Now it still wont chamber my reloads, still shoots Federal 150 grain hunting fine, and if I slap the bolt with my hand once, sometimes twice, the Creedmoor brass will extract.

        Just measured Headspace on unfired Creedmoor its at or under 0 pretty much on an RCBS headspace gauge. Fired brass is running plus .005.

        I dont know.

        I dont have HS gauges to check go/no go/field

        Dont want to send it back a third time.

        Think I need a second set of skills to check it out.

          What does the Federal 150 stuff measure on the case gauge?

          Also, can he tell you what "match" reamer he used and how many chambers were cut with it before yours?

          I might take you up on that.

          Hold that thought.

        What do the loaded ammo necks measure and the fired necks measure?

          I'll check.

        Have you tried Federal Gold Medal Match in 168gr ammo in it? I believe part of the problem your having is that the throat isn't long enough for the Creedmoor stuff. Also since the pre-64 actions are control round feed once the extractor pulls off the case rim while trying to extract it's very hard to get it to pop back over the rim and extract, actually most times you have to tap out with a cleaning rod.

          Haven't been able to find FGMM local (Cabelas).

          The extractor isnt releasing off the case.

          Once I slap the bolt to full rotation the brass pulls right out and would eject away if I didn't catch it.

          In the mean time got my M40/.223 together with 32 coats of hand rubbing.

          Will try to zero this weekend

        Are the primers flattened or cratered on the Creedmoor ammo? Maybe there's a pressure difference between the different companys? Have you measured the unfired cases? case diameter, oal, Shoulder, etc.
        Just curious how much different the cases are.

          No significant cratering/pressure signs.

          Unfired cases are near SAAMI spec on an RCBS headspace mic.

          They are about plus .005 after firing using same mic.

          I could measure them on a Hornady to get real numbers.

          If you look in the M70 build thread I posted you can see some ammo diagrams the builder did trying to diagnose the problem.

          My reloads and Creedmoors ammo is "fat" just above the case head.

          Phil, i think that you need to do a chamber cast with cerrosafe to see exactly what the chamber dimensions are.

            Same gunsmith built my Model 70, it had issues as well. Wouldn't extract and is picky about what ammo it chambers even though I sent him some ammo I wanted to shoot.
            Instead of rolling the dice and sending it back to him for repairs I decided to send it to someone I trusted and knew would fix the extraction problem.
            As far as the chamber goes, it is what it is. No M72 Match for me, I have to stick with FGMM.
