Using hard cast 300-grain Saeco (#058, 454 SWC-GC) bullet that leaves the barrel at 1400-1550 ft/sec, how high is the confidence level that this bullet will penetrate "through-and-through" on elk - including one shoulder - at 135 yards? At 165 yards?
Confidence on that would be really high. I plugged an elk with a .44 mag and 250 grain Keith Hard cast,two shots. Both went through. Killed a bunch of deer with that load too and only recovered one bullet, after it had gone length wise through the deer....almost 5 ft. of penetration.
Be aware however that damage from hard cast at those speeds is minimal compared to a regular high speed rifle.Small hole in and out, small wound channel, takes a little longer for hydraulics to give out. Aim for bone if you get the chance.
