PJ,
I have a 14" Hunter that, based upon your post, I think I would be a good canidate to have rechambered to the 444 Marlin.
On that data that you posted, what bullet were you using with that load? I am wondering how the 444 Marlin would do with a .430 Lee 310 grain gas check?
Has anyone had any experience with the T/C muzzle tamer on the 444 Marlin?
