RE: 45acp Question
I wouldn' t have a problem using it for shots inside 30 yards for deer with good jacketed hollowpoints. However, I don' t think I' d want to use it for hogs. My dad told me some stories when he was growing up about using a .45 for killing hogs to butcher. It took a between the eyes head shot to put them down, at about 10 feet. Hogs are tough critters.
They aren' t legal in Oklahoma due to the restriction that handgun cartridges have to have a case length of 1 1/2" , which virtually eliminates all semi-auto calibers.
