I only went up to 26.0gr of Lever with that bullet and stopped because it was so severely overgassed compared to everything else that rifle would shoot. If one were only going to use that one load though, it would make sense to just turn the gas down and run with it.
FWIW 26.0gr with that 75gr BTHP averaged 2766 fps in my 16" AR "recce" rifle. In the same rifle with that bullet, TAC will do 2850 and AA2460 will do 2820 fps, both with less gas to deal with. I settled on 23.5gr of Benchmark with that bullet for 2680 fps, giving up some velocity for better accuracy and repeatability throughout the year.
