I've shot two deer with my Kimber CDP Custom using 230gr Gold Dots loaded to +P. 45 ACP has been a great caliber based on those experiences. No tracking, deer fell within 10 yards of where shot. It really is a fun experience and to me combines the best of bow-hunting (limited range) with the effectiveness of a firearm. ( I should preface that statement with the fact that I cannot hit poop with my bow - I practice and practice, getting consistent fist sized groups out to 30 yards, but when I've dropped the hammer on deer or hogs, I always find my arrow with no blood on it sticking in the ground, having choked yet again!) Full energy dump in chest cavity, did not penetrate far side. Neither were very big deer.
