I just loaded up some 158gr. Hornady SJHP's last night for starter loads for my new Ruger SP101 (2.25"). Loaded 10 with 3.7gr's of W-231, and 10 with 4.0gr. of W-231, with a COAL of 1.455 and light crimp on the cannelure. Luckily, I have several manuals and was very shocked to see a significant difference in powder recommendations between Hornady's 3rd Edition for this boolit, and my Sierra binder. Hornady listed starting load with Winchester 231 as the 3.7gr's that I loaded, up to a max of 5.4grs (designated +P), and the Sierra binder listed a starting load in almost the +P rating. Decided to go on the side of caution and start with the lower Hornady numbers (since I was using Hornady boolits.) It doesn't look like a whole lot of powder in the case that is for sure. I used a RCBS 3 Carbide die set and seated and crimped in one step--no case bulging. Would upload pictures of completed bullets, but have horrible luck taking close up pics with my camera. Here is a stock photo of boolit used.

Interesting. The Hornady 8th Edition runs from 3.7 to 4.9 gr of W231 (4.9 +P). I'd be interested to hear how these loads work for you. I load Hornady 158 gr SWC/LRN with 3.6 gr of W231 and would have no problem loading the 158 gr SJ in the 4.0 to 4.5 gr range.
