Some times the pictures get that way - especially when shooting vermin. The varmint sites I attend try to keep the worse of it down but there are times when a bit of mung creeps into a video. The video "nothing but chunks" comes to mind.
When I saw the title, I thought, yes, a .300 WSM will kill a fox, if you hit him right - then, 'probably messy', but there was no video. I was surprised to see it had been removed.
