RE: 7MM's in Alaska
In the 25 years i lived in and hunted all over Alaska, i never felt undergunned with a 7mm Rem. Mag. loaded with 175NP's in my hands. There's not a brown bear alive, or anything else in Alaska that icouldn't drop with it...
I can't imagine someone thinking that you need a 30 cal gun to backup a properly loaded 7 mag... as the 7 mag. on a big bear will easily do anything the 30 will.... Includeing penetrate just as deeply to break a bear down...
