Many a true word is spoken in jest
, the drop with any size shot, even SG would be substantial at that range.
Regarding shooter accuracy and prowess, think of it this way: over ordinary ranges of say up to 50 yards the usable size of the pattern is probably around 3 feet, obviously much less the closer you get and as little as just over a foot at 15 yards or so, therefore shooter skill really plays a huge part.
At 90 yards there will be nothing resembling what we know and refer to as a pattern ! Instead if it were even possible to measure a circle into which 70% of the shot end up, it would without a shadow of a doubt be several yards wide. You begin to see that shot placement is of secondary importance to luck.
This is why old school Pool stands with ridiculous distance birds were more often than not won by chaps you didn't recognise carrying their guns with a sling & swivel.
