I haven't been overwhelmed with them in the past, but accuracy has been OK (1.5MOA or a little better) but, and it is a big but, I have only shot them for accuracy in 1 rifle, with 1 powder (TAC). For SHTF, I would be very happy with that combo. It shoots well in my lightweight chrome lined carbines that I have not tested from the bench for accuracy, a can on the 100 yard line is in serious trouble from any position if I do my part.
They seem to expand and be an effective hunting/SD bullet (see Molons and skypups postings on the matter) and are reasonably price compared with other heavyweight .224 bullets and Borg has gotten respectable accuracy out of them reloading with Rx-15.
So, based upon the body of eveidence, I decided to buy a few K more and give them another try. I also liquidated 600 rounds of factory 223 pressure ammo (I kept my 3131 and 193) and replaced it with much more effective reloads for the stash, and accuracy is just as good (better really) than most 55gr FMJ loads of any type.
Just my opinions, and probably worth less than you paid for it.
