Have an IPSC (pistol only) match this weekend and will shoot production. I shot limited 10 with my Kimber, but qualify for production (I think, I am actually new to all this). The 3 gun match classification I shoot is Tac Optics.
Right now I am mostly still trying to get loads that function and shoot accurately in my guns. The power floor in Tac Optics and minor production is kinda low, I think I could drop powder in my pistol load one more notch. That load shoots good, but is smokey. For shotgun, I will stick to the 3dram eq load I have of 1 1/8oz of shot, with 18gr of red dot. Might try green dot, but this load has been good so far. Functions and knocks down everything I have shot with it. Does kick some though. For rifle I load a 55gr fmj over a starting load of 2460. Anything over 100yds, I use factory 55gr fmj. So far my match prep has paid off with zero malfunctions (except the first 3 gun, where i hadn't checked the sights on the Glock and those 40 yd pepper poppers). Every match I see shooters struggling with equipment failures. I am lucky to be able to test fire my guns at home.
