Manson gauge horizontal technique???

[GH-16]

The Manson & Hosford gauges are based on the same basic design. The key to getting accurate measurements with them is to not hold on to the gauge itself firmly. Notice in Dr. Drew's picture he is using several loops of string to keep the gauge out of his hand. The Hosford uses a large metal loop that you only use one finger loosely in. Watch Jon Hosford's videos on his web site using his gauge.

Doctor Drew's method of holding the gauge steady is similar to mine. I use a helper and it works just fine in the horizontal position. The "helper" holds the barrels steady on a flat surface and you handle the operation of the Manson gauge. Vertical demands a lot of paraphernalia to hang the gauge, way too much effort at a gun show or auction.
