RE: Most versatile
I read in Successful Hunter this month an article by Ed Stevenson stating he wanted his BROWN BEAR hunters to use a 30/06 with 200 grain nosler partions or a like bullet (X, failsafe ect). His point being most hunters are not accustom to a jolt from a .338 win mag. I would use a .45/70, .35 whelan, 9.3 x 62 or 9.3x74. These would all be milder recoiling and have a tremendous punch. I guess 40 years as a brown bear guide would qualify him to make such a statement.
