I have a few boxes of 154 and 196. The idea was to use it in my AMD65 for home defense as it would be slower because of its weight, plus be slower in the 11" barrel - the purpose being less over-penetration. This didn't really pan out once I studied the velocities and energies involved. Imagine a 196gr pointed bullet at 1000 fps - it carries a lot of energy and potential for penetration. So then I thought that I would go the opposite direction and get an SKS with 20" barrel to actually get more velocity out of them, but I hated the SKS and abandoned that idea. Now I still have the AMD65 but I also have a ZPAP92 pistol, so I'm keeping the heavy loads around for further deliberation.
I wish I had more of them, and like you say, we might not see them again, at least until we get the White House back and can get these orders repealed.
