Hi guys this is pretty much my first topic thread here. Sorry if this question has been asked before. I've been hunting for roughly 24 years. Mostly in the south east, my biggest calibur rifle was the 30.06. About 5 years ago Ive been fortunate enough to have a thriving business and I've expanded my hunting to pretty much all over the US. I plan on making the leap to Alaska first and then Africa. Right now I own a few 300s in 300 win mag and a few WSMs. I'm looking to up the power because I've been invited on a couple of coastal brown bear hunts, elk hunting and like I said my dad and I want to do Africa within the next 3 or 4 years. So of these bone crushers which do you feel would be the best overall gun for the applications above. I already plan to top what ever I decide to purchase with the new Zeiss 5-25x50 hd scope. You alls feed back on these 3 rounds would be greatly appreciated. A little more, I like synthetic stock guns. I don't mind muzzle breaks or rifles in this calibur 6.5-7 lbs.
