One calls for 10.8-12.1 grain of power pistol at 1.253” OAL. The other shows 12.2-12.6 gn of power pistol at 1.245” OAL.

It was concerning that the shorter round had the higher charge. Do those seem reasonable?

I’m thinking of starting with 11 gn at 1.25” and moving up in .1 gn increments. Does that sound about right?

I'd move up in 0.2 gr increments unless you have a really nice scale. Most scales are only good for +/-0.1 gr so when you weigh out say 11.2 gr it could potentially be 11.1, 11.2 or 11.3 even. 0.2 gr increments will save you bullets for testing and should give you a noticeable difference between load points. After you find something you like you can try 0.1 gr up or down of it for better results, but it may not make that much of a difference in handguns.

I have some 240 gr Sierra JHP's that are the same length as the 230 gr XTP's. I am going to load them up with power pistol from 12.1 to 12.5 gr. I think I shaved off a tenth of a grain to compensate for the 10 gr heavier bullet and the fact that this is a pretty hot round and I don't want to get too risky. I haven't got around to loading them up yet though so no results.
