This is just my opinion so take it for what it is. Unless you are on an entry team subsonic 300 Blk is a neat range toy but not much else. I own one, and from time to time I load subs up in it, but from what I have seen beyond shooting people or paper those subs are pretty useless.

I have a 1/4" mild steel plate set up at the edge of the woods on my property. I shoot at it often with 22 LR and it reports and nice "twang" back. 22 doesn't do anything but knock off the paint, 9mm and 45 dent it, 5.56, 7.62x39, 17 hmr, 22 mag, and 300 BLK supersonic all have bored a hole right through it. As I said, it is mild steel. 220 gr subsonic 300 blk doesn't dent it, doesn't penetrate it, in fact doesn't do anything to it except knock off paint just like the 22 LR. When 17 hmr and 22 mag are going through the steel and subsonic 300 blk isn't even denting it, (which as I said 230gr 45 ACP does) it tells me that there just isn't much of anything behind that bullet.

As I said, neat toy but beyond that not much utility.

This is a legitimate ballistics test, its FBI grade mild steel.

MrM4 on NFAtalk sells them and usually discounts for members. And it's user servicable so you can buy lead rounds.
