I'm going to purchase a brush gun to augment my existing hunting rifle (30-06). Open sights, lever action style. Probably a Marlin. I've hunted with a 30-30 in the past, and it was the good old standby. But, I'll be using the gun for elk as well (maybe bear). I think I'd like a little more thump. But, would also like it to be serviceable for deer as well by going with a smaller grain bullet. I'm giving serious consideration to the .444, 45-70, and maybe the 308/338 Marlin Express (although those I'm concerned about ammo, as only Hornady seems to make them). Does anybody have any experience and advice with the larger caliber lever actions?
