If anyone has load info on a 125 gr. .357 using 4227, I'd appreciate it. Interpolation says 19-20 gr., but my reloading manual does not actually call out any load data for the 4227 until up to 146 gr. Any ideas why? BTW, after trying the 'hotter' powder loads that many of you sent me, I'm back to 4227. Reason is simply that I shoot better groups with it. I found that the 16.5-17.0 gr. range gives me the most consistent results using 158 gr. XTP's (which I can get on sale for $6.71/100, BTW). But, they ran out of 158's and so I picked up some 125's for about the same price only to get home and find that the pounds of powder I have don't get called out for the 125 gr. slugs..... Hmmm.

4227 is a relatively slow powder for pistol bullets. I've never seen it used for anything but heavy magnum loads for .357 on up. I'd imagine that the lighter bullets do not provide enough pressure for decent ignition. The heavier bullets, probably build a better pressure curve. I've noticed LOTS of unburnt powder in light 4227 pistol loads. While not commonly referred to like cratered primers, I've always taken this as a sign that a particular combination may not be completely appropriate. Anyway, this doesn't directly answer your question. I'll try to check some of my reloading manuals and see what I can dig up. I'll email after the holiday weekend if I can dig something up. Rick.
