I shoot the 120 gr ttsx at 3175 fps with 1 gr under max load of big game from the Nosler book. This is from a rem 700 ss sps with a 24" barrel. Only about .75 moa, but it will do for hunting. I have not pushed it yet, but could get over 3200 I believe. The gun prefers the 120 gr Nosler BT, but at those speeds I want a mono metal bullet.
