it is possable to reline it all the way through the chamber (theres some 1/2" liner witch just makes it) this will stop the liner from shooting out the gun . best way to get accuracy with a worn lee enfield is a throat sized cast bullet most are going to be around .314-.316 its best to slug and see unlike jacketed bullets cast will swage down so a over size cast will not be overpressure one because cast bullet loads are lower pressure to start with and they dont wear the barrel down at all if any they are also not as harsh on the gun like jacketed loads not to mention if you can get it wheel weight alloy is good enough and can be had free or next to nothing i dont pay a thing for my bullets. i do have to pay for my gas checks though and theres no .311 gas checks you got to use .308 witch i think would not protect the bullet i use .32(.323) on my bullest there pushed through my .316 sizer this sizes the gas check and locks it on
