I was at a respected gun shop in Bay City yesterday and was talking to one of the sales guys there. We got on the subject of barrel/chamber heating. He said that if I shot my 300WSM more than 3 shots A DAY, I'd just be chasing my tail trying to pattern it. I explained I let the gun cool for 3 minutes between shots, be he said the round is so hot, and it heats up the chamber/barrel so much that only 3 shots a day should be shot. I kinda politely agreed with him and left the store. Now, I've shot a couple hundred rounds through it and have triangular groups. If the gun was hot, why aren't I getting stringing patterns? Am I crazy? Or is this guy wrong?
