If it were me I would rather have something like Hornady's TAP Barrier load which uses the GMX bullet. Goes through barriers and transfers energy better. Of course the treaties signed many years ago most likely prohibit the use of that bullet. It is why you don't sign stupid treaties.
The Barnes TSX 70gr loaded to 5.56NATO pressures (not .223) is supposed to be the shiznit, both for barriers as well as terminally.
The SOST is also known as the Mk318, right? From what I've heard the Marines like it.
I try to be diverse: part of my "rainy day" ammo stash---that I don't touch---is 200rds of the Silver State Armory 70gr TSX 5.56NATO, 200rds of Mk318/SOST, and 200rds of Mk262 (a mix of Mod 0 and Mod 1).
