A couple of things. It's a coated bullet, so it will act differently than a jacketed bullet. Also, the coatings can flake off, and blow back into the gas ports of an AR.
Since it is a non-jacketed bullet, try it as a super first (1200-1300 fps) and make sure it's stable. Work your speeds down and keep watching for stability. Some lead bullets require more twist to stabilize properly. At sub speeds, this could be a good bullet once you worked up a load for it.
