Polecat, Forgot to mention I did run a few 125gr. Sierra spitzers through my 303 and they worked just fine as far as over all length. Accuracy was good as far as I went and that was a mild load of 3031 giving a little under 2300fps. For what ever reason I wasn't real keen on useing that bullet at that time just tried them to see if the spitzer profile on the shorter bullet would work through the action.
