I typically shoot poorly Iin the heat, and not so great in the cold, but I never really thought much about being sore or tired.. This morning I shot our sporting clays league, very tired, and with sore shoulders and shot my best score ever, even though I didn't expect to do well.. I didn't really think about the targets, I just walked to the station, loaded,the gun, called the targets and fired. I didn't even notice the extra recoil from the 1-1/8oz 1300fps AA sporting clays loads. When you get into the zone nothing seems to matter.
