I've got both inline and traditional side locks.Thompson Centers.The inline is scoped and str ictley for hunting.The Recomended max load is 150gr of pyro or black. I only use 120gr because thats all my speed loaders will hold!...Side locks are older T.C.'s and not good candidates for "magnum"loads.. At one time I did load my .45 cal Cherokee with some 240gr connicals and a stiff load of black.The darn thing about tore my shoulder off(it only weighs 6lbs)...Won't do that again.....Keep your powder dry.....
