Over 10 years ago I purchased a 12 gauge skeets bore gauge that I have been using. But as my collection increased I had need for a gauge to measure 10ga down to 28ga. Upon good recommendations from this board I purchased two gauges from Centerfire Ranch. One to measure 10ga - 16ga and another for 20ga and 28ga. I just tested my original .700 skeets truing ring with the new ring and they are less than a thousandth off. Both my gauges indicate the same diameter.

I'm glad there is another option, but I am very happy with the ones from Centerfire Ranch.
