I did not hunt with the 75 grainers. What happened is, I tried them with an AR w/ 1-9 twist. This was back in the crunch and that was all I could get. What happened is they were accurate to 100 yds but started spreading out at 200 yds. This was mainly due to the twist rate. A 1-7 is much better for the 75-80 grain bullets. You can use them probably if you don't make log shots. I just purchased that one box, because I had read about this happening. That is why the Military went to the 1-7 twist. It is not recommended to hunt with, because most manufacturers think deer, hogs, and don't consider coyote hunters. It fine for coyotes. Depending upon your twist rate,you may be ok.
