Round 1 included SR7625, Tightgroup, WSF and WIN 231. All rounds were mixed brass, 124 gr. Montana Gold Dots. Federal Primers. OAL of 1.130. Around 150 ft elevation. 60 Degrees Fahrenheit. The first five rounds were just to see which was the softest. I took pumpkins and blasted away. Nice easy targets so I could warm up and get a feel for the rounds recoil. I got my first surprise for the day. I would have assumed it would have been tightgroup as it is the fastest burning of the group Instead it was SR7625 which is a medium burner. Softest Recoil. SR7625 Tightgroup WSF WIN 231 Next it was time to put up some targets and test for accuracy. Again I was surprised. I thought for sure it was going to be WSF closely followed by Tightgroup. I was shocked when Tightgroup ended up to be the most inaccurate of the bunch. It's just every one (except one guy) in my IDPA group that shoots 9mm uses tightgroup. Group think I guess. When I bought my 9mm I just went straight to tightgroup because they were all using it. It has only been this year that I moved to WSF. Most Accurate WIN 231 SR7625 WSF Tightgroup My Win 231 group was good enough that I almost wonder if I should keep looking at other powders. I have had good luck with WIN 231 with the 40SW so these results shouldn't have really surprised me. Next for Win 231 test out to 25 yards. Time to get the next batch ready for testing.
