The previous owner had Tom make up the shells and then never fired the gun.
I am always wary about shooting other's loads so plan on talking to Tom before doing anything. I do think they are loaded with the Primex powder and are the faster of the paradox loads.
Hopefully William Evans will respond to my email and shed a little light on the gun and proper loads.
CC, i would certainly be interested in your mold if I am able to load my own cartridges.
Also, what shot loads would be appropriate for this gun? I have a couple boxes of vintage Peters 7/8oz paper shells that would be nice to use if appropriate.
