He's one of the best long range shotgunners in the world.
55 yards is where he might pick up his gun.

It's not my thing, but it is HIS thing.

The only agenda might be that any crippling in the UK is frowned upon. So he wants some minimum # of penetrating hits at whatever range.
I didn't watch the video. (slow internet at 55 degrees north) Was he shooting at old CD's by his truck shed?
