As I remember, it seems that there were feeding issues with the 300 Savage having something to do with the neck.
A result of this testing resulted in the birth of the 308 Winchester.
Now, I probably don’t have all of the details correct concerning the issue because it’s been awhile since I read that but someone on here would know and could refresh my memory.


> what a older engineer at Federal Cartridge explained to me in detail was the 300 Savage was an excellent candidate to use in a machine gun and the U.S. military almost used the 300 Savage instead of the 308 Winchester, but Washington dirty politics and money under the table made the decision for our military to use the 308 Winchester instead. and now today its name seems to have change too ? a Grin and a head shake


I have read and heard from actual users that the U.S. military had more than a few Browning .30 caliber machineguns jam when they got hot and the rim would tear off a sticking 30-06 case. The 7.62x51 case was designed with a much heavier/thicker rim and base than the 30-06, probably done so in order to reduce the frequency of jams due to torn rims.
