I've loaded and shot well over the 1K mark of the 200 gr hp and not been dissatisfied in a 645 (also the 158 gr .357s and 115 gr 9mm). That said, I have been shooting the Meister bullets. They appear to be made a little smoother - more like factory jacketed stuff. Accurate? Yes. Cheaper? Yes. I hope you have as good of kuck.
