Bad QC
I'm afraid I have to agree with Sunray, I've had a P14 Centurion in 300 Win Mag which came originaly with a .303 cal barrel when it was a Enfield P14, when I found the accuracy to be poor with factory ammo, I slugged the barrel it miked out to .312 thous of an ins. instead of .308, kind of sloppy if you ask me. Then I got a P17 which had been re-chambered to 308 Win. the chamber was so out of spec. that you shaved brass with factory ammo, when you tried to resize the brass to reload it, got rid of that in a hurry also.
I don't own anything center-fire I can't reload for.
