I tested a few loads this weekend in my CZ 75SA Target. This gun is my primary range and IDPA gun. All loads were tested with 6 rounds each, from a rest at 7 yds. Yes, I know she's shooting a little high and left. I have the windage adjusted now (I think), need to talk to the CS shop about different front sight so I can get it shooting POA/POI at 7-10yds.
The load that worked the best was 124gr plated RN with 4.5gr of W231 and a COL of 1.145
Oddly, my 115gr loads shoot significantly better in my 75B than my 75SA Target.
