How does it compare to Hornady TAP 75grain .223? Bullet different? Thank You.

Cheaper in the Blue box and ya get 50 rounds for under 20 bucks or close!
and its accurate

I will add that it is VERY accurate and should be just about the next best thing to MK262 and Hornady 5.56 TAP for rifles with a 1/9 or better twist.  Also keep in mind that BH blue box is regarded as being better quality than most newly mfr ammo.

I shot 200 rounds of this stuff last week and give it a big +1!

There is no difference whatsoever in the Hornady BULLET, no matter what brand of ammunition it's loaded in Black Hills, Hornady Match or Hornady TAP, the bullet remains the same match hollow-point boat-tail sold by Hornady, (note: NOT to be confused with the Hornady 75grn, polymer tipped A-MAX bullet)

Just like there is no difference between the latest MK 262 Mod "whatever" loaded bullet (unlike the original Nosler 77grn. OTM bullet, that's been discontinued) which is the Sierra 77grn. MatchKing, whether sold by Federal Gold medal or Black Hills the "matchking" is the same bullet.
