AI 6br Primer Test

[AR-180]

Today, I went to the range to see if I could find a primer that will work with an AI that has a larger firing pin. The primers tested left to right were Winchester #41, Winchester SR, Federal 205, CCI 450, CCI BR-4, and Remington 7.5 BR.

The load for each is 28.3 of IMR 4166, Norma brass, and a 107 SMK. I have set up a notification for a small firing pin bolt assembly at Mile High. Are there any other options with regards to rifle or AI retailer?

Send it out to be bushed and firing pin turned down

Can an AI bolt be bushed as easily as a rem700 clone? My smith worked at AI chambering barrels for a few years, he runs lrp 65cm brass due to the pin in his AT. I told him to Bush it as well, he said it's not that easy with an AI. Idk........my atx is small firing pin from factory.

A relatively frequent complaint with M700 and Accuracy International actions (and others) are cratered primers with factory made ammunition. The root cause of this is from excessive clearance between the striker and the hole through the bolt face. When fired, the primer cup flows into the void...
