I was at the range yesterday checking the scope on my .300 win mag and was talking to another guy who was shooting one(not to many 300 mag shooters here in florida).He was telling me that he had hunted most north american species and many animals in africa with his.I was telling him that I was really sold mine as i went to get a .270 in a browning a-bolt and came home with a .300 mag in a ruger m77 all weather basically because I can hunt anything in north america with it and since I drive a truck all over the country I never know what might become possible down the road.They closed the bears to hunting in florida a few years ago and I have never hunted them but they are talking about opening a season again in the next few years.Any way this guy told me that a .300 mag was no good for bear and I think that is a bunch of crap.With a 45-70, .444, .450 you would have to wait until a bear is much closer to you to do what a 300 would do at say 150 yards and I really would hate to piss off a bear at 20 feet.maybe I think I have more gun than I do what do you guys think.
