FX .177 stx liner?

Very accurate with the right ammo. I changed my barrel liner and probe out from .25 to .177 on my Impact turned my power wheel from 5 down to 1 and shot a couple half inch groups at 50 yards. Then I got serious and immediately after shot a 1/4inch group. So accurate I would have to say yes. Think I was shooting the heavier 10.3 JSB pellet in the low 900s.
 
My stx liner was accurate but god knows how? After a couple of hundred pellets I decided to remove the mod and see what was inside, nothing other than pellet shavings. Rodding a pellet through and the reason became obvious, the internal finish was the worse I have ever seen, After spending a few hours I did manage to get it smooth, I don’t think it made much difference to accuracy but consistency was better and it gave me more confidence.
