My practice is to rotate 3 - 5 rifles/pistols to keep things from getting too hot.
No need to stress the barrel or alter poi's. Others may vary.
I agree. I never let my barrels get smoking hot. Sure, I'll post those 10 shot groups, but those are shot just as they would be in slow fire competition. 1 shot/minute. I was checking out the superlites yesterday. Pretty sweet rifles....
