Bed is made... no holes in the spread from hot casings or barrels.

Good grief. The ignorance on this thread is strong.

Have you ever actually shot a .223 or .308 semiauto rifle? I've seen a .223 ejected cartridge go down the front of a girl's shirt. Other than her jumping around and screaming, there was no effect. Not even really a 1st-degree burn.

Have you ever had a hot casing from a rifle after a couple hundred rounds have been put through it at cyclic ROF? It’s hotter than hell and will put a 2nd degree on you especially if it goes down the back of your blouse. Just for clarification:
M-14
M-16A2
M-60D
M-240B
MP5
M4
M79
M203
M2HB (single and twins)
GAU 17
M242

These are just a few weapons I am infinitely familiar with. Comes with 20 years of Naval training. 15 of that in NAVSPECWAR.

I always wear long sleeve shirts, button collars, a cap to keep the hot brass out of my glasses. I did get a mouth full of hot 9mm brass from a SEAL buddy trying to shoot an AR-15 9mm as fast as possible. I was behind and right. The spew of brass came pretty fast. It didn't have a nice brass deflector of the style offered on current CMMG 9mm AR-15 uppers today. As you noted, the hot brass is uncomfortable (especially down a shirt).
