The 5.56 TAP round that is red polymer tipped is shit for LEO except in the most unusual circumstances like some hostage rescue or something. If is nothing more than Hornady's V-Max varmint bullet that barely penetrates and horribly disintegrates in the first three to four inches. It was NEVER developed for law enforcement or self defense. It just looks tactical with its red poly tip. It is a GIMMICK.
The Hornady TAP round that is 75-gr is an OTM round and it is OK but is an icepick at 100-yards because of velocity and the OTM isn't a hollow point.
I've seen .223 Gold Dot 75-gr video where the round (fired from an 11.5" SBR) went thru a car windshield then ballistic gel and drove 19" with 80% weight retention.
The ONLY bullets I am as confident in (other than the Gold Dot) are the Swift Scirocco which is a unicorn in 5.56, and the Barnes all-copper if you expect that you might need barrier blind ammo.
The problem with the BARNES copper bullet is the it is quite long for its weight and thusly needs a faster twist. If you shoot heavier than 62 gr copper you have to step up to a 1:8" or a 1:7" barrel. But damn, as far as barrier blind the BARNES will not self destruct nearly as much as a cupro-nickle-clad lead core bullet/
Dj~ I hope your wife has the 75-gr OTM TAP because the other is very questionable IMO.
