Looking for a longer range load to tackle elk with. I have the 460 No Execuses conical shooting pretty well over 80 grains of 777. I am concerned that this round may drop substantially at 150yds which is about as far as I am interested in shooting open sights. I need a Washington legal all lead. I can shoot sabots as long as the projectile is all lead. Leaning towards the Prescision bullet Elite HP. Any other recommendations.
