Other advice I have seen is minimum 150gr expanding NOT fragmenting. They have very thick skin and fragmenting rounds can break up on impact.Biggest population in UK is in Herefordshire. World record weight was taken there, 518 lbs. We have a lot in Sussex, but they are very shy, almost entirely nocturnal, best taken lamping. It would be a very good idea for the guy with the lamp to have a back-up gun just in case. As I have said elsewhere, 5cwt of pissed off pig coming at you at 40mph with mayhem and murder in mind can take a lot of stopping. TAC 50BMG anyone?
