lad i know uses .314 cast bullets with great success....
you can make cast bigger bullets from your molds by placing heat resistant aluminium tape on the inside of the molds .
i done this myself and it works a treat
yanks over on cast boolits call it beagling

The throat of mine slugs at .314, I shoot .316 diameter cast lead bullets through it. If I use jacketed it's going to be .311 which is the standard .303 size due to the odd way they measured it.
First, they made a hole.
It measured .303" diameter.
Then, they put grooves in it.
THAT made ANOTHER diameter that was bigger, namely anything between .311" and .316".
Not odd, just the way they measured stuff back then.
Same with .577" and the .600" bullet.
The 45-70 Govt with the 457" diameter bullet.
......and so on.
The average .44cal BP revolver shoots a ball anything from .451" to .457" diameter.
It all harks back the days of black powder and deep-groove rifling.

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.
measure the inside of a fired ppu case it mic at .313 so thinking ill need aleast that size in lead ??

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.
