I've just got into Contender hunting this year, but stumbled across the Barns 110 gn TAC-TX bullet which i've been reloading over RL7 and been very happy with. I'm shooting ~ 2500 fps in a 14" barrel. I started with recipes published by Speer for their 110gn bullets and stopped before I hit their max velocities of ~2700 fps based on primer pressure indications and energy. Brass still looks good after 4 reloads, but I am only neck sizing. The bullet is designed to function at the lower 300 whisper/blackout velocities (full expansion at 1300-1400 fps, or ~400 yards) and very well suited to slower moving 30-30 loads in pistol barrels. I didn't spend any time trying to wring the last bit of accuracy out of the load, but usually end up with ~1" groups at the range at 100 yards off a bench.
I reloaded the Barnes flat tip copper 150gn and never got it much faster then 2150 with a variety of powders. Based on the minimum full expansion velocity for that load the max range was ~150 yards.
