    I have an AR-30 with a 30" Rock barrel that I want to rechamber in an Improved version of the 338 LM but have no clue as to the pros and cons of the various versions.

    I can use all help you are willing to give.

    I went with the 338AX. The ability to get fireformed brass ready to load from Kirby was a huge plus. Just send him any brand 338 Lapua brass you prefer and he will fireform it for a small fee. He also now has Jamison 338AX headstamped brass.He sells the reloading dies made with the same reamer that does your chamber. Not to mention hes a hell of a smith and great guy to deal with.

    338 Lapua Magn
