Is there a suppport group??

That's the one I bought from Brownell's more than a year ago for the same price (I think).

Hello, Bill? Please explain the better method...

The method involves using the Manson gauge in a horizontal position with the barrels in a vise, not too good for gun show use unless you have a table. I already have a hanging ring on the end opposite the micrometer. You may need to install one in the hole supplied. This ring should be large enough to conveniently run your finger through it to support that end without exerting side pressure. Zero the micrometer with the gauge in a horizontal position, holding the non micrometer rod at the ball end while zeroing. Run the non micrometer rod into the barrel and read your micrometer at any point in the barrel. Notice there is no problem with wavering readings as long as you use the ring to support the non micrometer end. The vise held barrels eliminate the wavering and false readings we get when using the hanging method. The disadvantage is that the barrels must be rotated in the vise to measure different surfaces of the barrels. I still like this method better than the hanging method when I have access to padded vises. I have not seen a vise that rotates around the horizontal axis, but that vise would be ideal in that the vise could be rotated to measure all surfaces of the barrels without removing the barrels from the vise.

Jon Hosford's beautiful new bore gauge works by a similar method, but measures a bunch of gauges and comes in a fitted wood box. Jon is a great guy. When I told him I owned a Manson gauge and couldn't afford one of his great tools, he showed me how to use my $100 gauge to work like his. Now who else would do that? He will probably be at the Southern demonstrating his gauge. Stop by and say "hi".
