OK. I ask because I let my hunting rigs cool pretty good between every two shots. Mimic the cold bore shots for hunting. Range/competition gun I keep the gun cool enough, but pay attention how its doing with warmth on the barrel.
A suggestion. You can limit component expense by first finding pressure with your selected powders, and getting an idea in that phase which powder is working the best. Then back off a grain and start the tuning by seating depth in 2 spots. Just off the touch of the lands, and .020 off. Trying to limp a non cooperating powder by eeking on it .2/10ths a grain is a waste of time, money, and money. You are turning cash into noise! LOL
