I've been reading posts and looking at you-tube vids on long range stuff (200 yards) and was wondering what would be the poi difference between a .177 at 11.5 fpe and one at say 10.5fpe? Maybe there's a formula for this?

At 200yds I'd guess at saying everything is in the lap of the Gods.

Theoretically, using iSnipe, JSB 8.44gn pellet. (zero wind, ISA atmospherics,Alt 250')

785 fps (11.55fpe) drop =260 inches
750 fps (10.55fpe) drop =291 inches

So about 2 1/2 feet.

Fair old drop then.
