45Taurus, i just got back from testing, and W231 and 185XTPs are a winning combination for me. I typed 6.3, but meant my starting load was 6.5. At 10yards, i had about a 2" group, a decent load but was lacking. At 6.8, all 10 shots were within 1.2", every single one touching, maybe 0.5" below Point of aim, but damn it was fantastic. At 7.1, i had one really odd flyer, went 4" left, but the remaining 9 shots were still fantastic, grouped about 1.5", dead center, so for me, 6.8-7.1 is a good spot it seems. I didnt get to chrono them since I went to my indoor range, but i will probably set my PD to throw 6.9 and will feel completely good with a 0.1 increment in either direction. I was extremely happy with my results, and have no problem loading up all I have with W231 honestly. I am gonna do one more batch, at 6.9, probably 20bullets, test 10 again at 10yards, and then do 10 at 20yards to see what they do with a little further distance.
