One of the viewers made a suggestion that I should fire 1 round a piece in each pistol and measure the brass. At first I thought wow that is a lot of work but my dedication to the viewers proved to be what I needed to get this done.

OOps sorry about that Shadow, I will try to bring only new fresh and do a better search next time.
mr.revolverguy, there's nothing to be sorry for! Always glad to see if the data matches and performance as it relates to what others see.
It is all good! ;D
