I'm going to try some H4350 with the 75 V-MAX next probably, but for the 80 SBT (which I've been using with about 39.8 of IMR 4064), and maybe even the 85 Sierra GK (HPBT) I'm real tempted now to try RL-19. We killed 2 g-hogs with the RL-19/70gr Nosler load the other evening, longest one was 157.5 yards which isn't much. Missed one at 327.5 that I really wanted - bad! My fault though, not the gun's.
