I have a Model 25-2 built in 1962. It had oversized throats of .456 and would not shoot small enough groups for my bullseye work. So, I sent it back to Smith & Wesson and had them replace the cylinder with a new one. The new cylinder is stainless steel, so now I have a "Pinto" gun that looks very nice. They charged mew $250 for a new cylinder and it took a few months to happen. However, here are my results, I now had a revolver that will shoot 10 shots at 50 yards into a 2.7 inch group, here is the proof....



My load was a 180 grain cast SWC (shortened H&G 68 style) over 6.2 grains of Power Pistol and Federal Large Pistol primers.
