I'm just starting to shoot USPSA at our club - before this year our club didn't run matches. I'm going to continue to compete in that and also continue in my primary competitive endeavor which is NRA Action Pistol - until it goes away.
The aspects of USPSA, steel challenge, and GSSF that I'm least enthusiastic about is the fact that each round doesn't count. Oh, I know if you are going to be competitive in these events you aren't going to be shooting much more than the minimum shots per stage, but the pressure for a first round hit isn't the same as it is when you only have 6 rounds to take down 6 plates at 25yards.
That is the aspect I was commenting on.
