[QUOTE="Stiletto150, post: 2630082, member: 70044"] I have an idea. Buy an infrared thermometer for $25 on Amazon or somewhere. I found tons of uses for cooking with it. Measure the same spot at the tenon of the barrel and the tip of the barrel. Before you shoot and then after your shot. That's if your barrel has metal on both sides to take a measure since it's carbon wrapped. #1 Shot- Then let it cool. (Whatever time you like~5-10min.) Take #2. Repeat the temperature procedure. Take #3 and repeat the procedure. This should prove any barrel heat-up issue. My initial hypothesis is this: if you take 5min between shots 1 and 2. I bet the 3rd shot can't be taken until 7-15 min to cool back to the optimum first and second temperature. You also may want to check that the barrel is still free-floated at shots #3 #4 #5. I don't think it's an ammo issue since it's repeatable with factory ammo and the odds of the 3rd cartridge always being off would be statistically improbable. [/QUOTE]
