Expanding FMJ

It appears that there may be a solution to the problem of troops being forced to use ball ammunition in their sidearms. Personally, I think the answer is to remove the prohibition but this may suffice in the meantime.

Known as the Federal EFMJ for “expanding full metal jacket” the round would appear to be a gift from above to the soldier on the ground. It is fully jacketed, yet expands like a hollow point upon impact.

It works by having a piece of encased lead with a tiny nylon/rubber plug. When it strikes its target, it cannot fill up at the front since it’s encased. Instead, it begins to (for lack of a better word) “smush up” the entire round. How it begins its expansion so diametrically opposed to a standard hollow point and its reliance on fluid hydraulics is that the EFMJ operates solely on impact/kinetic input to the front of the bullet.

Yeah, a very technical description, isn't it? The advantage is that it not only expands better than FMJ ammo but it also appears to surpass the problem of hollow-point ammo getting plugged by material, etc and thus failing to expand. Be nice to see some side-by-side testing to lend credence to the claims.

Now all they have to do is get the military to test and adopt it (don't hold your breath) and then move on to getting open tip ammo approved for the M16 series. Sometime next century maybe?
