Vulcan .22 Smooth Twist Ernest rowe installed

One day I was removing shroud from my stock berral and it was stuck on my gun tried everything to get it off. Finally I removed end cap stuck 2 medal rods down it by doing this I could stop the threads from spinning. If you have a Vulcan you'd know what I mean but yeah one of my medal rods went down the berral and I didn't know it. This scratched and gouged my berral out so I sent to Ernest and there was no possible fix. Then he installed .22 Smooth Twist the berral is far more accurate than my CZ berral much easier to take care of too.
 
None of the good barrel brands are better than the rest. LW, CZ, SR, TJ, BSA etc all have a spectrum of accuracy. The best examples of each of them are excellent and you will also find ones that are below average with every brand.

Some of it is to do with how well it is machined and fitted to the action and how well the gun is tuned for the barrel, pellet, speed, reg setting etc. 

As the barrel was machined and fitted by Ernest in this case, it's no surprise that there was a noticeable increase in accuracy.
