Witch match to use

Heelo ,witch match would be the best to use for our 3 gun compettition,that would matc our old scoring .

Most 3 gun competitions are scored with time plus points.
Your example is showing scoring of paper target which 3 gun most normally doesn’t do.
If you are trying to integrate some type of hit factor scoring then you could play around with the Hit Factor match type.
If you are interested, you could search “3 gun” in Practiscore results and see what all the matches use.

Best regards
