>I wonder how many pure PE or steel plates will actually be rated under 07
We're gonna see a lot of .06 holdouts with the steel armor crowd. RF1 calls for 3,250ft/s, which is beyond even some 9lb steel plates like those from Predator. You will need to use harder, likely more brittle "alloys" (AR650, AR680, or Tacscorp's AR700) or up the thickness. NAS3 M193 will easily get you past that, so steel's plainly screwed unless you're in an area stuck in 1998 and everybody's running M855 for no reason.
>PE should meet RF1 still
Easier than the NIJ 0101.06 test, since multi-hit against M80 is reduced from six to three and M193 is not a problem for PE. 7.62x39 MSC is only a problem for very old (think 0101.03 era, pre-2000) PE plates.
>steel plates would have trouble in the weight department
We're gonna see 10lb plates with spall coating.
>Pure PE should fold to regular M855
Of course, but you also need to account for various engagement distances and the new breed of "enhanced PE" M855-rated plates. Combat Systems RF2 (4lb) and the rumored LTC 28855 (<4lb).
>Hopefully handloading autists will develop some good loads sooner or later
Whatever happened to the dagny dagger?
>For both NIJ and the military, threats are going to be considered by whats likely not by whats possible
There's a philosophical split between conventional military and SOCOM. The former selected M2AP for the ESAPI, and the NIJ for IV too, because it proxies exceptionally well for the vast majority of common threats. If you can stop M2AP @ 2,880ft/s you can stop just about any steel core 7.62x51 or 7.62x54. SOCOM opts for a less overkill approach (B-32 API).
>NIJ still considers M2AP the level IV threat even though its obsolete in every way
For proxy reasons. If you can stop M2AP you can stop anything CONUS that would be a realistic threat for a SWAT officer. Tungsten really only comes up OCONUS, but murphy's law can be a bitch here n' there.
