I shot an IPSC match on Saturday . . . .
(1.) Gotta' SLOW DOWN sometimes. To begin the first stage of the match, it took me 5 shots to knock down 2 pepper poppers at 10 yards (that in turn deployed some bobbing targets, upon which I got decent hits). I don't usually get nervous before a match, but I often shoot too fast on the very first string of fire on the very first stage before I settle down.
(2.) On the very last stage (of 7) I did a speed in-battery reload and somehow induced a malfunction. I had to strip the mag out of the gun and start all over. I had 12 "a zone" hits out of 12 rounds fired, but a stage that should've taken me about 12 seconds took me 20+.
You can only learn from experience if you pay attention!
