I have a Ruger Super Redhawk with a 7 1/2" barrel last season I took a deer at 165YDS. USING BuffaloBore 240 gr. GoldDot ammo I did not know the distance I guessed it at 80-90 yds only after the shot I measured with a Leupold range finder the BuffaloBore ammo shoots flat and hits very hard the deer dropped immediately and did not flinch I hope this helps chad
