Its a better self defense round than the much hyped M855 which tends to over penetrate.
The M855 was designed to cycle the M249 SAW and to penetrate WARPAC light armor and helmets at 1000 meters.
In return it leaves a lot of other things on the table.
Dont get me wrong M855 is not a bad round and I stock some of it myself, but that fast varmit round will serve you quite well for protection.
Any Hornady round is consoidered a premium round and one measure of how well you did could be , how much did it go up in the current bubble?
The answer for your ammo is only slightly, whereas lake city XM855 went up by a factor of 2.5
So that hornady IMO that hornady is a better deal at 1.15/rd than the XM855 is at $1/rd ( it used ot be available in summer at 40 cents a round all day long).
