We expected a few new chamberings after Marlin bought H&R (then Rem bought Marlin). And the 'Why don't we get' started right out with the 'Marlin' calibers! Since Handi's love rimmed cartridges, my first thought was the Marlin .308 and the .338! But big corporations do things that don't make sense to the rest of us. But that is not answering the first question, who makes the barrels. I think we need Tim to help us out on that one. Dinny is right, Marlin makes some or all of them now (I think), but we need someone who know definatively. 44 Man
