57 - I carry H&K USP compact in .45 ACP with me on every tracking and try to deliver coupe de grace with it if possible - it also comes at hand when crawling after wounded boars in a thick stuff (no way you can cary a rifle in hand at that moment) - neck shots are preferable as you said. Mainly I use 230gr FMJ for finisher (I do carry a spare mag with 180gr JHP for a defence boar scenario).
