"168 grain Sierra Matchking
43.6 grains of IMR 4895"

This seems warmish to me. 41.5 grains of H4895 pushing a SMK168 is considered a classic load for the M1A/M14. Not saying 43.6 can't be done, or even that it's unsafe, but I certainly wouldn't start there. (I'm also not saying that H4895 and IMR4895 are interchangeable.) Hornady would not have you loading IMR4895 with a 168 grain bullet past 41.4 grains, and Sierra would have you stop at 41.3. Go figure.
