Did not work well enough to use - Pachmayr Competition Speed Loader 5-Shot S&W J Frame/Ruger LCR, Ruger SP101/Taurus 85/ Rossi 68

I tried this on Smith & Wesson Models 49, 637, and 638. It took too much finesse to avoid cylinder release and actually get shells into cylinder, then it was too difficult to hold cylinder and turn difficult-to-turn release. I've used speed loaders like this on larger revolvers and had no trouble. Have yet to find one that works well on J frames. Gonna try speed strips.
