Assuming you've confirmed your AR handles Tula .223 well enough and you want to buy a few bricks to tuck away in a dark corner of the basement for "just in case" ammo... Has anyone fired Tula .223 55 or 62 grain hollow points into any kind of test medium? Do they come apart really bad? Expand at all? Penetration? Bottom line, if you were FORCED to have to choose either the FMJ or HP to shoot a bad guy after 'the apocalypse', which would be the better choice?
