I guess after reading most of the reply's some have been taken offense to my question. I recently just signed up on this site and had no idea you guys had beaten this subject to death. Yes I have made up my mind on what makes sense and don't make sense. Maybe I should of wrote the guestion like what do think about the new calibers and the use of them. I personally hunt with a 300 win mag it's the gun that fits me and 30 years ago people would have asked the same question about that too. My basis behind the question is related to all the hunters that show up in camp with a new gun because it was suppose to kill better. Well 95% can't shoot the thing at all. And of course that is their faults. So in regards to beating a dead horse my apologies, but I never heard a pro comment other than being new and something to try out why a guy would want to trade in his old rifle for one. Yeah I'm curious about the new market of magnums and have researched them. But the question was writin badly and after rereading it I wanted to change it. Personally I don't care a person shoots as long as they shoot it well.
