As far as what people say about the .300 RUM being finicky, a friend of mine looking for a new rifle asked for advice on a caliber for whitetails. I told him that the .270 Win. would be perfect for him. He then asked why I shoot a .300 RUM. I told him it was like driving a hot rod. You are putting up with self-induced problems in the quest for ultimate performance. If you do not want to put up with a shoulder thumping, barrel eroding, powder burner that requires more tolerance this is not the caliber for you.

The .300 RUM is like a redhead. Both are hard to handle but once you do, HOOOWEEEE!!!!
