I wouldnt give up on your event just yet. If you attracted 34 shooters for the Sat registered shoot, I would say you were quite successful. We managed to get to a measly 22 shooters for our last event and considering the work that goes into organizing and setting up the event it is hardly worthwhile. We had mostly sunshine for the weekend while at Beverhill they managed to attract almost 60 shooters in the rain.
We try and keep our pricing in the range of .60/.65 cents per target, we have more variety in targets than I have seen elsewhere and the prizes and meals are great. Part of the problem is that there are two events almost every weekend so attendance is split. Good for shooters, not so good for the organizers. We had previously committed to attend the Kamloops shoot, otherwise we would have been at your shoot.
Regarding registered vs fun shoots, it seems attendance is higher if it is a registered shoot. Not sure why that is but its a fact and overall, the cost of the shoot has very little to do with attendance as long as you put on a good event.
