When we went the other day the 30 minutes felt about right. There are plenty of target holders and size wise some hold 2x a4 targets and some a single a3. The printed targets have different layouts but most have numerous target circles so there's plenty to go at.
There are also LOADS of spinners & knock downs which you can move around & set at different distances.
Tek thi big coyt though, it gets chilly in there!![]()
