In a recent post I reported a problem extracting fired cases from my Navy Arms .308 Enfield.I was firing Portugese milsurp ammo.Today I tried some Winchester 150gr.soft points and had no problems.One or two rounds were a bit sticky to get out but otherwise everything was good.Accuracy was fine.I had gotten some case dimensions from a site on the net and the Portugese ammo measured .005" undersize at the bottom of the case.I haven`t had a chance to compare the Winchester cases to the milsurp yet.
