It is hard to deny the price point of the 55gr Hornady interlocks. $67.99/500 at midsouth is looking pretty good. The 69 and 77 SMK and TMK's are twice that. Although they do shoot better than the 55's. I remember taking 4 of my AR's out to develop some loads with the 77TMK's and every one of them loved that bullet. Sub moa 10 shot groups was the norm. Its hard to make those bullets shoot poorly.
