Today's lesson, kids ...

After years of stuff getting behind my "safety glass" glasses, sometimes with some really close calls, I decided goggles are the way to go, and not just at the range.

Terry said that. He's a slow learner.

Women aren't the only ones vulnerable to hot brass. I was involved in some cropping in Zimbabwe and while shooting impala at night over the front of the landcruiser, I worked the bolt and ejected a spent .30/06 shell which went right down my PH's collar. (he was driving)

He wasn't happy . . . although the boys in the back were mightily amused.

I took a defensive handgun class a while ago.  There was also a married couple in the class.  He was much taller than she.  During the shooting portions of the class, we would be standing in a line firing at our individual targets, and her brass would fly up into her husband's face.  By the end of the class he had quite a few powder streaks on his face.  I'm not sure why he didn't move to the other side of her or something . . . .

I have several scars from hot rifle brass getting stuck against my skin.  It was all 5.56mm.  The pistol brass doesn't bother me too much; it cools down pretty quickly.

I am told that autoloader brass is hotter than manually-ejected brass.

Apparently the few seconds between firing and ejection allows heat to be transferred to the chamber with manual ejection.  With autoloaders, there's no time for this and the brass is as hot as at the instant of firing.

I never tested that.  Any comments?

And if you get some brass down your shirt from unloading a revolver you probably shouldn't be handling guns.

^ True, true.

Do you look like this?

I would say that that is very true based on my experience with both autoloaders and revolvers.

That is my experience as well.

One of the problems that's hindered the adoption of plastic case ammo is the fact that metal casings carry away some of the chamber heat upon ejection, plastic casings not so much. Becomes a rather larger issue in full autos.
At least that's what I've read, not done the math.

Makes me wonder if they could come up with a coating that would sublimate to gas under heat.  I guess it would be hard to find something that would be stable under all possible storage conditions and not be corrosive or toxic.

Sounds very logical, and someone's point about pistol casings seems valid.  The time I got a shell on the back of my neck it was a nice big heavy hot .30-06 case out of the next guy's Garand in the prone stage.  My shooting jacket prevented it from wandering around too much and I just scooped it away with my trigger hand, but for that two seconds it was hell.  My first high-power match, and when I arrived, I kinda wondered how come so many were wearing campaign hats.  I had nothing but a billed cap.  At the time I was still "corporate" and hadn't grown a pony tail.

One of the few times I learned a little faster than usual.
