I'm working on a 20" rifle build at the moment that will wear a TA11H. I think he'll be an exception to the above and get zero'd with M193. Still thinking about it, though...
Hell I'd zero that one with the 77gr IMI round. It'll get even better terminal performance at range out of the 20" barrel.
Not being critical at all, but I am slightly surprised by the number of M4C folks who zero for either a 75gr or a 77gr load. The IMI Razor is my second go-to ammo, after the Mk318. I have as much of it as I do of the Mk318. My only deciding factor was what level of penetration should I expect to need in a "SHTF" or home-defense scenario? I calculated that the Mk318 had a decent mix of barrier penetration and good terminal ballistics. Sorry, didn't mean to sidetrack into an ammo discussion.
