FYI ... This post contains load data notfound in reloading manuals. Just because it has worked in my firearm does not mean it will work in yours.

I just bought a Governor, but already have a Judge. The Judge is moving on, but the load development I started with it will continue with the Governor. I am using 444 Marlin cases, Precision 410 shot wads, 7.5 to 8.0 gr Unique & 3ea. 0.357” dia mini bullets I make by putting 0000 buckshot (0.380” dia) through a 357 sizing die.
Why you ask? Because I own pistol/rifle reloading equipment. So far loadings chrono at 700 to 800 fps. With a 4” spread of bullets at 7 yrd. I have not had sufficient range time to re-confirm and refine the results. Now with the stronger Governor I may be able to increase the Unique charge into the 8.5 to 9.0 gr range.

It has been over a year since I recorded the initial testing. I will post up more info as I get it from trips to the range.

Until then I am interested in any loads others have come up with.
