Garrett, By far the bulk of my jacketed loads have used the Hornady 85 grain JHP XTP. And I've found excellent loads using it with Unique around 4.0-4.5 grains; and Win 231 @ 4.0 grains. With the Hornady XTP 100 grainer, I like less than 4.0 grains which gives me similar accuracy but at reduced velocity. For my money, with jacketed bullets, that 85 gr. XTP is a winner. I found a deal on them a yr ago and promptly bought 1200!! Generally, I save the 100 gr XTP's for a 1920 vintage .32-20 Winchester M92 that really perks with them and save the 85's for the revolvers.
My next powder try out will be with WSF just to see how it does...it's a bit slower than Unique so should be in the ball-park, and God knows, it measures better.
The Hornady swagged 90 gr. SWC does almost as good with half a grain less of Unique...groups running down close to 2" at 25 yds. I haven't pushed them due to leading concerns as they mic 0.314".
But for real economy and accuracy, I've found the RCBS mold # 32-100 gr LSWC to be superb. I size to 0.312", lube with LLA at first then with 50-50 thru my Lyman 450. I'm using Starline cases (the early Federal factory cases were junk with 25% splitting on first firing) & have had equal luck with Federal or WSP caps. Accurate bullet molds also makes a first rate mold that's very similar to the RCBS mold...I have 'em both and they're interchangeable when loading. My alloy is air cooled wheel weights with a pinch of tin to help fill out. 700 degrees keeps my Lyman 20# furnace filling out the molds, BTW.
Bull-X used to make a LSWC with a hard lube that was almost as accurate with the same loads, and I'd check with Missouri Bullet Co. for their offering as well. With any commercial bullet, using that damnable hard lube, you may have to resort to LLA & Lee's swirl lubing technique to keep leading down unless you really push them hard. All my loads are mid-level with that 4.0 gr Unique giving me just over 1000 fps from my 4-5/8 Mini-Vaquero and a bit more from the 5-1/2" SS. Same for the Win 231 load.
As always, these are MY loads, work up if you're interested after consulting a GOOD manual and considering all the pressure implications.
