I presume the potential 'problems' you listed above is why the quality Button Rifled Barrel Manufacturers Air Gauge their Barrels and Grade them accordingly? Their 'select' or 'ultra match' grades are held to some impressive tolerances so at least you know what you are buying.

Hi,
Apologies, I was talking to Wade from Shilen at the Shot show, and the way he described it to me was that they are more concerned with the dimensions of the starting hole, hence the usefulness of the air gauge. Obviously the more consistent that hole is the more consistent the force of the button is through the barrel, and the more consistent the dimensions and twist rate will be from barrel to barrel.
he described the difference in Match to Super match to me as the amount of time spent lapping to alleviate tight and loose spots and getting a consistent feel on the lap through the barrel. I suppose it follows suit that they would use a diiferent form of air gauge gauge again, and I'm sorry for going off on one about this.
