If your intent in shooting is to stop cinder blocks with a 5.56mm, well, OK, then M855 is worth the extra cost...
But if you're looking to put holes in paper, then M855 doesn't really matter.
If you're looking to stop people in your house, then there are better choices. One of the issues with M855 in actual combat is that it simply goes right through targets (bad guys) without doing much damage because it doesn't fragment or spread...
If you think you might have to stop people who are hiding behind barriers with your 5.56...then, M855 would be worth the extra cost...
But while I've got a few thousand round of M855, I stock up on, and plink with, M193. It's cheaper. And the range to which I belong doesn't allow the M855...the ammo is constrained just a bit...
Great place, by the way...
