Smooth twists?

Depends if you believe the hype that was around when it was launched. It hasnt proven to be the game changer it was hailed to be

I think this was half the problem, I hasten to add I have no opinion either way as not used one

I have a Crown in sub 12. Once the s---e from the grease used during manufacture has passed through the action and the barrel has been cleaned (polished with VFG felts and blue paste,) the gun is as accurate as my Steyr and Anschutz. I have heard of people saying "not to clean" the STX barrel assembly. What a load of b-----s.
The gun is superb to shoot and will shortly be used for bench rest shooting armed with a 12 mag scope. If it wasn't up to the job I would use another of my target rifles. The interior of the barrel, when polished, resembles a spiral galaxy when looking into the light. Following the polishing process, a few of the normal pull throughs after every tin keeps on top of the accuracy, which is nothing short of stunning. Personally, I love it.

Following yet another practise session of bench rest today, I would advise any Smooth Twist "X" barrel owner to give the tube a few pull throughs after approximately 300 pellets. Mine started to go off but was back to excellent after the LT1/Napier pull through treatment (x3). Incidentally, my barrel does not like anything but pellets manufactured by JSB, which is not surprising considering that the assembly was apparently designed to run with these pellets.
I also owned an Impact and had both .177 and .22 barrels. The X Twist, has for me, proved to be more accurate than the original Smoothtwist in .177.
