    .243 Win. for the AR platform.

    As you suggest, believing anyone selling something at a gun show is like believing someone selling something at a carnival. Its foolish. Do it, the 243 I mean. So what if barrel life is less than inferior performing cartridges. That's why. 243 outperforms them. No free lunch. Ever. Tires...

    JP Enhanced Bolt benifits?

    Well the Armalite bolt has been working a long time. Try it. It'll work for you too. Await the seasoning time for the "HP" (how bolts should be designed anyway) configured bolt.

    DPMS 260 pierced primer - bolt bushing?

    Cratering in auto-loaders will affect ejection. Think. Part of the primer is sticking into the firing pin hole in the bolt face. that adversely affects smooth cycling. Cratering in autos is a no go.

    FAL 308 vs AR15 in 308 - how do they stack up?

    DPMS 260 pierced primer - bolt bushing?

    My "drop-in" fix is an Armalite bolt, carrier, pin and DPMS barrel extension. Works. And works flawlessly. Head spaces correctly, shoots accurately, reliable. Runs like a sewing machine. ORD is right to feel we shouldn't do it. I do shit all the time I'm not supposed to do. Its how I...

    JP Enhanced Bolt benifits?

    I know. John Paul and I argued about this issue two years ago. Took him awhile but I'm glad someone purporting to have an "enhanced" bolt actually produces a bolt with enhancements. By the way; an attendant issue is firing pin reliability. In the 6.5x47 I built we bushed the bolt and turned...

    There are a general rules of shooting, obviously, but there is room for exceptions: If a v8 in one car is outperformed by a v6 in another, its okay though the performance is an exception. The headstamp is general. "Holy Toledo, Batman!" performance is peculiar to the piece producing it, and...
