I have killed deer with Horn a day SST in 12 ga (very destructive even at 75 yards), same in 20 ga, didnt expand at 18 yards, and Remington Accutip in both(excellent). I have sold my slug guns and gone to single shot straight wall cartridge rifles. Last fall, 44 mag (drt at 68 yards) and next year 45-70.
Many killed with Foster slugs by Winchester, Fed, and Rem over the years.
