If you go to UK Varminting one of the guys (JR from Border Barrels) has some inside info' on it. The pig had escaped from a farm and had been causing a nuisance to home owners, so he asked somebody to shoot it.
The really worrying thing was that the father and guide covered the son “with high Powered rifles” while he had 16 shots at it with the .50 cal pistol.(only 8 hit it). All sounds a bit bull$1th to me, 16 rounds out of a .50 cal pistol even for a adult would give the hands battering let alone a 11 year old boy, if they had rifles why did they not just shot it humanely with a rifle?
