And,for those that may be interested another quirk of firearms history. During WWI , Enfield designed a new bolt action rifle called the P14 Enfield which was also a basic Mauser design copy. Britain did not have the resources to make it so the design was sent to the USA. Colt and many other companys made the rifle in 303 cal and shipped then to the UK. When the US joined the war they modified them to 30-06 cal. and called it the P17 ( for 1917) and that was the weapon that the "Doughboys" used, hence the nickname " doughboys rifle". See Sgt. York Movie.
It just so happens that the bolt face of a P14(303 british) is identical to that of the 300 Winchester Magnum. Therefore, I am the proud owner of a bull barrel P14 target rifle( rebarreled and stocked of course) that will out shoot my 50 cal. on a wind less day with moly coated match reloads.
Running around like a head with it's chicken cut off.
