I am going to be buying a rifle primarily for bear hunting this season. I think i want the weatherby vanguard s2 because of quality for the price. This rifle is available in .300WSM, .300 win mag, or .300 weatherby for the same price. Since i will be shooting alot of 178-200gr bullets i have ruled out the WSM and am trying to decide between the win mag and wby mag. My question is, is the wby mag really worth the added cost of ammo and limited availability really worth the extra 200 or so fps i could excpect? I dont expect to be shooting over 500yds
