Had a Remington M25 for over 25 years, but the headspace got too bad. Then found a nice 94CL and mounted a K3 Weaver. Really fun piece. Like Mike, I tried for years to find a Christy cylinder for a Colt SAA but was a day late a couple of times. Got lucky several years ago and found Ed's with a batch of factory 10" Contender barrels. My most fun .25 yet. I like it best with iron sights. Factory Winchesters get within 5 fps of my 94CL yet have no magnum blast. It fits on the front seat and makes the perfect jackrabbit combination. Either cast or Speer 75 over 4227 or 4198, that's all you need.
