I wish that I had access to a chronograph. Perhaps after hunting season, I can work something out locally to chronograph my reduced power loads. I'd like to shoot the same load in a 12 gauge and my 10 gauge to measure the velocity decrease; which I think is sizeable.

Maybe someone can bring a chronograph to Flatwater next April.

I can see and feel reduced velocity when shooting the same 12 gauge load, in the 10 ga. Baker using the Gauge-Mate adapters. For the moment, I am increasing the SR7625 powder charge somewhat to try to reasonably increase the pressure/velocity up to a satisfactory level - without stressing the gun.

I had hoped for a more scientific solution, rather than this "trial & error" approach....
