The Hosford & Co. Bore Gauge is a simple to use, all-in-one bore measuring tool for 28ga to 10ga shotgun barrels. It features a large, easy to read dial, and is direct reading instead of measuring from zero like most other bore gauges on the market. Direct reading means that there is no math involved when measuring any barrel from 28ga to 10ga. The gauge is supplied with a precision zeroing block for the standard bore of 10ga, 12ga, 16ga, 20ga and 28ga. The gauge will over-travel enough to measure 8ga bores with some simple math. With over 16” of reach the Hosford & Co. Bore Gauge can measure most barrels in full when used from the chamber and the muzzle. Because of its reliability and ease of use, the Hosford & Co. Bore Gauge is the perfect tool for anyone from a professional gunsmith measuring large quantities of barrels to the amateur working on a much smaller scale.
