I doubt anyone can tell you that within a thou or so. If you have the barrel, slug it and measure the slug; then you'll know exactly what your barrel is.
OK, lets try this a different way. does anyone know what the advertized bore dimensions of the Crietiron barrel in 303 British are?. I want to know before I start sinking money for molds and
H&I dies to sieze the bullets. Thank you.
New Criterion barrels for the No. 4 are .303 bore and .314” groove, with rifled five grooves 1-10 LH twist, machined from gun barrel quality 4140 chrome moly steel with 0.010-short chamber for gunsmith headspacing, if you don’t have a selection of replacement bolt heads to do this in the usual way. The 4NFLD1 features a turned forward shoulder to enable indexing with a lathe. The 4NFLD-BW has a turned back shoulder with a series of breeching washers, enabling installation without a lathe. Barrels are available either Parkerized or in the white. I would expect their P14 barrels are rifled to the same specifications.
The ENEMY is listening.
HE wants to know what YOU know.
Keep it to yourself.
Thank you Outpost75 you provided exactly the info I was looking for. Didn't know about the turned forward or turned backward shoulders and breeching washers. Thanks very much. Frank
The p14 barrels are 0.314".
I've has used a few
Be well
