OK--this is probably one of the top dumb questions I've ever asked--but it really has me wondering.
Yesterday I was shooting my AR creedmoor build when an ejected shell bounced off a board and hit my hand--burning it cause it was so hot. Later while shooting my ruger american 270 I noticed the spent cases coming out of the chamber were cool to the touch even when the barrel was quite warm. I know the AR sends gas back into the receiver--but I still don't see how that can account for such a marked difference. Why is there such a big difference?
