Just Wondering:40-82 Silhouette diagram

[Kurt]

Sgt.

Here is a drawing of a very rare Ballard Everlasting chamber that is as close as I could get it. I know you are asking for a .40 caliber but I have been shooting this chambered in my CPA 44-1/2. It is a mild recoiling round that is very accurate. I have a second being build that will make silhouette weight. This is strictly a PP chamber and will not except a groove diameter GG bullet, but that can be changed.
The Datum of .5050" is incorrect, it should be .5010" This drawing did not have the Datum updated.
