Reloads and hot cases

spm815
I have been reloading for my Browning A-bolt in 30-06. The 180 gr Hornadys and 54 gr IMR4350 have been shooting really well. When I shot the same loads through my Remington 7400 the cases were so hot after firing I could not pick them up. I tried the Browning again and the cases were not hot at all. What's the deal? The 7400 was not as accurate, but I expected that. Is there a problem shooting that load through the rifle? The cases looked fine, just really hot. Thanks for any help and sorry for the long post.

    Hello 2 things number 1 each rifle is different so max load in one rifle may be over max in the other. this said I suspect that what you see is in an auto rifle the case doesnot have time to use the chamber of the barrel as a heat sink because it ejects so fast after the shot is fired. In a bolt action the case transfers some of the heat from burning powder in the case to the chamber area of the barrel in the time it takes you to operate the bolt after the shot.

    Good post, I would have never thought of it on my own.

    If they don't trust us with guns, how can we trust them with the government?

    This even applies to a .22 semi-automatic. When I was a kid, we were down at the river in swimming trunks and a guy fired off a string of shots with a .22 as fast as he could. Everytime an empty shell hit this other kid in the back, it raised a welt! [:0]
