Went to the range last Saturday about 3:30 in the afternoon here in Augusta, GA. I was shooting my Contenders and the barrels never cooled off. Had some fun with the .357 Magnum and the .300 Savage Rimmed though. Working on my shooting form more than for groups. Sweat was dripping into my eyes so bad I had to give up shooting around 4:15. After 35 years down South, you would think this Mid-Westerner would be acclimated to this heat. NOT!
