I’ve had both 150 & 180 grain Barnes break elk & boar bones over 500 yards from 7 Mag & 300 Weatherby so impact velocities similar to a 30-06 under 300 yards - I’m a believer in 180 grain Barnes 2400-2700 FPS on just about anything walking. Large cow at 240 yds last season 10’ of blood on far side with a chunk of heart tissue & a 15 yard slide downhill in the snow. Use the monolithIc 30-06 With no worries.
