223 No Go or Field Gauge in Prescott Area?
« on: November 08, 2021, 07:44:17 pm »
Anyone have gauges in the prescott area or maybe a gunsmith recommendation? I put together an AR recently and had a couple case separations. Would like to rule out the brass being the cause because it's handloads and I already made 1000 of them.

    LRK Mechanical off Miller Valley Parkway has done good work for me.

    However, if it were me and I couldn't find any gauges to borrow, I would probably buy some as I am guessing you will need them again.

    alot of gunsmiths wont touch ammo or may know little about ammo. suprising but its true. if i were you and didnt want to bring the rifle down to me, get the gauges from manson reamers or forster. then get a headspace comparator from whidden/hornady/SAC to reference how much excessive headspace you have from brass to chamber. you maybe oversizing. it happens quite often for standard dies and general reloading knowledge.

    every rifle i build this is standard info i supply after the test shots so NOTHING comes back to say anything is out of spec.

    Thanks.

    What I do is take the barrel in one hand, bolt in the other and chamber a sized piece of brass and then a fired piece of brass. If the fired brass chambers I go look for my field gauge but I lost it when I moved. The brass is machine gun fired surplus mixed headstamp stuff so could be oversized or brittle.

    No. You could benefit from a reloading class and a thorough inspection.

    I found my gauges and headspace is fine, it's the brass unfortunately.
