Maybe its my rifle, but loading 62g of H4831 (called AR2213sc here) gets me only to 3050fps or so with the 130 cup and cores. Its mild. I can't get much more in than that so I use 4350 instead for just under 3100fps.
I find the 4831 perfect for the 150 and 160 though, 59 and 57.5 respectively give 2950 and about 2800.
Barrel is 23.5 inches on a Zastava Mauser.
