There's saying the pistol is sighted to hit centrally on a 'lollipopped' target at 6m. That is only really useful info if you know what the target was; and I suppose to some extent what the pellets were - though I'm not sure how big a difference that would make?
How high above the point of aim is the point of impact at 6m?
We have always known there were two Britains: one extraordinarily pleasant, inhabited by mild, tolerant, kindly people; the other utterly disgusting, inhabited by brutal and malevolent louts. Auberon Waugh
