Quick Q: Double D recommended relining to 303. I thought this wasn't advised for higher pressure/power ? If this is ok, would it be fine relining a 6.5x53r, if things are kept moderate (factory ballistics)?

Cheers.

Relining weakens the rifle? Is this true? I would think the liner would be made of much better quality/stronger steel than the original barrel. I would not think the installation of the liner would be any less invasive to the strength of the weapon than boring the barrel open to, say .358, and removing so much steel. Can anyone explain this to me? Norman4

I enquired on relining my Lee Speed before re-chambering to 338/303 Nitro Express and no relining outfit or gunsmith would take the job for this very reason . It would have to be custom because relining companies stick to lower pressure jobs. The JES re-chambering was quite simple :the bore was just drilled out to 338 ,the 303 head-space stayed exactly the same with the 338/303 just a different bullet . The same thing as taking a 25-06 and re-boring it to a 30-06 ....Interestingly after re-boring I fired a box of 303 British Winchester hunting ammo out of the rifle to obtain the brass with no ill affects ( remember the headspace is exactly the same ) The groups with the 303 Ammo still hit into a 6-8" group at 100 yards with some keyholes but was no worse than the original shot out 303 bore . My 338/303 reloads in the new bore shoot cloverleafs now at 100 ; quite an improvement over the original !
