The only use for those stepped brass gauges is to hold in your fist when slugging someone!!

I bought the four gauge dial indicator bore gauge set made by Custom Shooting Products in Nebraska from Jacqua's over a quarter of a century ago, and ordered up the extra 10- and 16-gauge heads. I'm sure it has more then paid for itself over the years.

For the cost its hard to beat the Skeets gauges. Midway sells them also.

I'm with Researcher on this one.Considering that 12 ga. chambered
guns in Britain can start life with bores anywhere from .710 -.745
all that a stepped brass gauge tells you is that there is a hole at the end of the barrel!
I had a friend recently who took his very nice Lancaster Crown grade SLE to a neighbourhood gun shop and they broke out the brass gauge and told him it had no choke and his only option if he wanted some was to send it for choke tubes.Luckily he gave me a call before shipping and because the bores were .740 he had .005 in the right and .015 in the left. We averted a horror show....

"Relative to the bore diameter" is a concept that many who turn steps on brass bars simply can't comprehend. Many are learning indirectly without vast practice in mensuration because those lovely sets of choke tubes don't have the interchangability between guns and gun brands that they expect they should. Skeets is affordable; it works. Baker has the price; Galazan the price and the cachet. Pay what you wish but get something that "measures something" as Eightbore says.

I have a Skeets for everything but the nasty .410. Works fine.

A lot of people believe that if an instrument returns to zero, it's good stuff. What makes an instrument good, i.e., something that can be professionally certified, is accuracy throughout its range of measurement.

I loaned the Skeets to a friend in a machine shop. He doesn't certify, but he knows what he's looking at. He said the Skeets performed just fine on the tests he could throw at it.

I suspect that with any of the bore gauges, one will find more inaccuracy being generated by poor operation (careless zeroing, not pulling straight out of the bore) than there is inherent to the instrument.
