100 yard comps are very common with the bull at that distance being around 1 inch. There have been comps held at 200 yards but they are very uncommon, There used to be one held anually on the old 200 yard shorts range at bisley (roughly where the new shotgun layouts for the comonwealth games are now) IIRC. I belive this was shot on the old size NRA fullbore target.
