Re: Help me select which "Improved" version
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.
