300 win mag would be my vote - big enough for brown bear, overkill for deer and antelope
my accumark weighs around 9 1/2 pounds and i have a break on it so the recoil is no worse then a 243 win. and i have hand loads that will out shoot anything except a custom rifle and even some of those are out done. but hey thats why they make so many choices for us to have fun with
