Now stifle yourself and quit giggling...

LINK. No quantities but you can pretty well bet the 5.56 will be 855 or relatives 'cause Black Hills has the Mk 262 contract...:wry:
Until we get the new lead - free really GREEN rounds... :rolleyes:
I was involved in an indoor range clean up (lead levels through the roof...surprise, surprise) and an outdoor range cleanup (mining the backstop berms so that the high water table at the site would no longer be impacted) perhaps ten years ago. Anyway, the new GREEN rounds at that time, if I remember correctly, were also bad news...I wanna say cadmium, but I am not 100% on that. Maybe we need to go to those much talked about ice rounds...alright back to listening mode. Happy 4th everybody.
Don't forget to hug the bunnies before you shoot 'em...

It was quite a contrast to earning our CIB's a few years later, using very Earth-unfriendly depleted uranium 25mm. But it could have been worse - we didn't kill any desert tortoises or disturb any red-cocaded woodpecker nests.
1989 was the magic year. After three years I switched gears, became a tech, and spent ten years sampling, conducting chemical analysis, planning abatement's, doing spill response, cost estimating, and scheduling for toxic and hazardous substance projects (half-face, full-face, papr, scba, tyvek, saranex, and butyl rubber) which left some muscle memory for this non-EIB, five jump chump, who picked up a CAB the hard way (didn't get hurt though). I have been dabbling as an engineer in Hydraulics & Hydrology and Geotech (design, cost estimating, scheduling, project management) for the last 7, it's a lot easier on the old system than the industrial environmental stuff.
Lead has been around for a long, long time and I see no reason for changing things for this particular application...apply 'appropriate engineering controls transparent to the user' for the ranges and life goes on.

The difference in ballistics won't make much difference at CQC range (3-10 Meters). Of course, when training at longer ranges where differences in ballistic characteristics matters you have to use the good stuff.
There was another 5.56 round that we used in Germany for a while. It was all the rage with the guys who had used it down range in OIF but it was eventually discovered that in cold weather the brass had a nasty habit of rupturing in the chamber. I may have that backwards, I never actually got to use them, but the point is that these rounds were great in one environment and prone to catastrophic failure in the other.

It looks so deceptively simple, it's just metal and its tougher than duct tape. But then, as you correctly note, temperature, time, pressure, pH and gas compositions in the chamber/barrel and other items that I am not aware of all have their say. We goofed around with steel and aluminum in some of my classes in order to pick up on some of the common topics in materials: stress, strain, modulus of elasticity, poisson's ratio, hooke's law, etc., etc. It helps me look at carbon fiber arrows, motorcycle frames, engines, helicopters, and of course weapons in a new light... :wry: ...so many interesting things so little time.
