Bullet Caster said: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.
Hmmm...Last time I checked the .303 British is supposed to be between .311, and is still serviceable all the way up to .313. Hornadys 150 to 180 grain bullets in .312 might have fixed this.
But so does the conversion to 300Win Mag.
