303 bullet size

[gtpkeeper]

Is that .318" between the lands? If not you need a new barrel.

A friend of mine with a SMLE slugged his barrel and between the lands it came to .314". He had a mould made to that size. It wasn't cheap.

the two bands that stick out on the slug measure .318
it fired the ppu .311 fmj ok,

My friends rifle shoots the .311" copper jacketed bullet alright, but lead is not accurate with the standard size bullet which is why he had a mould made with a bigger diameter bullet. The SMLE he has got had been rebarrelled at some point and the rifling is square. The gun had been in storage somewhere and was packed in grease which had to be cleaned off.
Because of the age of the rifle he only shoots lead bullets to preserve the barrel life and downloads the cartridges.

If I remember correctly a gas check is needed on lead bulets for velocities over 1200fps otherwise the bullet will strip the rifling. (Ride over it).

NOE moulds do moulds off the shelf in most sizes, I've got three for the Enfield and he'll usually get them to you in less than a couple of weeks from the States.

That has little or no bearing on the bullet size needed. The casemouth will have been blown wider as the bullet was driven out and up the bore, then sprung back part of the way - practically impossible to know how much, unless you know the chamber neck i/d and the exact case wall thickness.

When you say you've slugged the bore, what method have you used?
