What may also be a good idea is to have a rifle team event arranged (teams nominated before the day) and shot on the day
Perhaps teams of 3 or maybe even pairs

I have a superb biathlon target with steel discs that have holes that go down from 12mm on disc 1 to 6mm on the final disc 5.

This would be ideal for a team match.
Shots through the holes cause a white flag to trip showing a hit and points are normally 1 for disc 1, 2 for disc 2 etc up to the final very difficult disc 5. So a max score over the 5 shots is: 15 if my sums are right or 45 for a team.

Food for thought - plenty of time to arrange
