I have been looking for a Smith 625 or older 25 for the 45 acp/auto rim. The newer 625s have a good reputation for accuracy but the older 25s for the little I have been able to learn can be more challenging. The size or oversized cylinder throats seems to be the problem most often with the model 25s. Can any of the members who have experience with these give any suggestions as to the dates of manufacture when Smith and Wesson would have made the model 25 with the .452 cylinder throats, or is this just the luck of the draw. I am set up to cast for the smaller throats and would like to use the same loads and not introduce a new variable to the inventory. I also prefer longer barrels and the 5 inch 625 is not easy to find. There are on the some of the acution sites model 25s which are not in the collector price range, and have 6 or 6 1/2 inch barrels. I am look for some gude lines to differential between the two, and to have some idea of what to expect before jumping in. My goal is accuracy first.
