I've been looking to get a big bore rifle for awhile now. I want something that I can take with me camping in Grizzly country. I've looked around and narrowed it down to the Marlin guide gun and the Henry all weather. Has anyone had any experience with either of these? If there is a better choice let me know. I definitely want a side ejection rifle, plus Henry and Marlin make good guns. I would want to handload for it so is one better at taking nuclear loads? I'd be using some 405 grain hard cast bullets. Also, how would a 45-70 compare to a 12 gauge with slugs at stopping a charging Grizzly? Let me know what you think.
