Which 300?

[L. Cooper]

If someone else loaded the rifle for you so that you didn't know which round you were shooting, you would never know which one it was. Neither would anything you shot with them.

If, and as others have said it's a big IF, you need one, pick a rifle you like. The rifle it comes in will make way more difference to your experience than will the cartridge.

The .300 Win has been around for over 50 years. It will be here for sure for another 50. Is that a factor?
