I would use the long colt before the acp,But yes it will take a deer at that range.Our you putting a scope on it?
I also have .45 ACP hollow points, but I definitely would use the .45 Colt Gold Dots. I don't have a scope on it but I believe I can keep in the kill zone up to 50 yards with it.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
