You are not talking to yourself. We are out there listening and interested. I've been curious as to what your problem was. Thanks or posting the conclusion. I am about ready to order a 4 inch Tracker in 45 Colt, Model 460, leaning toward stainless steel but still thinking about titanium. I was waiting to see what your conclusion was. I think I might have a similar problem with a Taurus 32 H&R Magnim UL. The guy I bought it from said it only fires in single action with certain kinds of ammo. He suspected hard primers. It has worked flawlessly with everything I put through it so I haven't worried about it. Back to the 45 colt. My concern with the Ti is the possibility of heavier bullets jumping the crimp in short cylinders and brass sticking with "warm" loads, since Ti is more flexible than steel, and of course comfort. I would love to hear how you are doing in these areas. I plan to load carfully working up to 45 ACP pressures as I and others have discussed on this forum and on handloads.com. Looking for 1100-1150 fps in a 255-265 grain bullet. I would love to know what bullet weights and velocities you are shooting , whether factory or handloads, and how you are doing in these areas. Is your gun steel or Ti and what does it weigh?
