Has anyone used the Tubbs system in their 454 casull rifle? I own a puma 92 that likes to foul and I called Tubbs on the phone and the person I talked to wasn't sure if their .452 pistol bullets would work in a rifle. He is going to ask someone else and get back to me, but I was just checking to see if anyone else has tried it themselves. I ordered some bullets for my 375 ruger that copper fouls real easy with barns bullets and heard good results in that application and figured what the heck and get some for the puma also.
