[QUOTE="jrock, post: 1327618, member: 78569"] I've done some temperature testing like you are hinting at. I did it on a hot summer day with no shade and found that waiting about 4 minutes between shots (#3 contour) kept my groups consistent. I used an inferred thermometer to measure the barrel temps while doing this and noted that the temperatures changes significantly along the barrel length. I picked a point just short of the end of the forearm where it seemed to be the hottest and monitored the temperature. I don't remember the numbers off the top of my head but I did write them down. That being said, I would let the grouping tell you when the barrel is too hot rather than go off a barrel temp. Temps will change on many different conditions and contours. Not coincidently, the stable temperature that gave good groupings was "warm" enough that you could hold onto the barrel without discomfort. [/QUOTE]
