Air-Gauged Barrel
What is meant by an "air-gauged barrel" and what is the advantage?

A air gauge is a accuratly sized cylinder with air ports out the side, when you put a calibrated amount of air pressure into the center, you get a flow rate that varies with the gap between the gauge and the bore. The lower the flow rate the closer the fit.
You can measure the variances in the bore diameter as the gauge is passed from one end to the other from the change in flow rate.
Does air gauging make the barrel better? No.
It only tells the manufacture what the variance is. Their tolerance level is what determines the quality (the guy that accepts .005 variance is using it (the phrase) as a sales tool, the guy that scraps anything with more than .0001 variance is using it as a quality control device) looking at those 2 examples of it's usage and tolerances levels, guess which catigory a $75 contured, threaded and shortchambered barrel is in compaired to a $200 blank from a top name barrel maker.
Some guys like a mag full of lead, I still prefer one round to the head.0 -
Tailgunner, thanks for the excellent explanation. Wait'll I lay this info on my shooting pals! BTW, were you an AF tailgunner? 0 -
Happy to help
