The seller who goes by the name of "Unloader" has been selling these bore gauges for a long time and makes a quality product at a reasonable price. He also makes cases for his gauges and makes wooden shell dismantlers. I have one of his shell dismantlers.

Mark have you measured 8 gauge bores with the hosford gauge? I have seriously considered purchasing it but wanted to insure it can accurately measure 8 gauge bores. If you had one you could get a .835 ring gauge and check the accuracy of the reading, but I would like to test it before I buy.

Eldon,

Yes, I have measured 8 gauge bores with the Hosford bore gauge. It does not come with a standard (calibration) ring for 8 gauge but calibrating it for 10 gauge puts it pretty darn close to perfect for 8 gauge.

Also, for most tasks an accurate differential is all that is required, i.e. the amount of choke constriction.
