I bought a barrel sizing kit for the thor bullet line to shoot in a hunt this year they come with bullet sizes 500,501,502,503 i think, my inline ruger shoots the .501 bullet after pushing them down tha barrel to find the propper fit. I like the preformance I get out of it and want to use it in one of my Renegade rifles same 50 cal. I cant take out the breech plug to push the wrong sizes out so I wonder if any body has slugged the barrel of one or knows about the seze of the Thompson 50 cal is. I guess I can push them down ontop of a charge and shoot them out to figure it out. any help would be appreciated.
