Re: how hot is hot?
O.K., today I found a reference to "how hot is too hot" on a Darrell Holand shooting video. He states that you should operate your barrel between 80 and 150 degrees. He also states that much above that can shorten barrel life. That was the original question I was trying to get which is great! Now to take a thermometer out and check to see what that feels like on the old hand.
