A simple, easy to make and accurate chamber gauge
A simple, easy to make and accurate chamber gauge:
Using a fired empty hull, preferrably plastic, squarely cut the crimped end off and make another square cut near the metal base. Clean off the cut edges. Measure the length. This is your gauge.
Insert the gauge into the empty chamber until it stops at the forcing cone. Use a small scale to see how deep the gauge is and add that depth to the length of the gauge and you have the chamber length.
Make for other gauges as needed.
I might add that I have a friends 10 gauge underlifter and it has 2 3/4 inch chambers. A "PARKER BROS. WEST MERIDEN, CT 10 A" 2 3/4" brass shell fits nicely but the more common "PARKER BROS. MERIDEN, CT 10 A" 2 7/8" stops 1/8" short of going all the way in.
Hope this helps.
