One of my favourite sayings is ... sharing is a sign of weakness
There has to be more options out there. How are we gonna keep this awesome sport alive if members have no where to shoot?
Welcome to the sad state of the Ontario gun scene. New gunnuts having doors shut in their face all day long by people who rant about how the government is killing the shooting scene. In southern Ontario you pretty much have to accept the high membership costs and jump through the hoops to shoot at wherever will take you.
Is Barrie still accepting members? Expensive and rules heavy, but that's where most of my shooting gets done when I visit Ontario. Probably quite a drive for you, but at least the facilities are really nice.
It seems like your looking for a non-private outdoor place to shoot which is very hard to come by these days, but some ranges I could recommend would be target sports located near highway 404 and stouffville rd, a little pricey but not crazy and they are pretty good guys in there. Or east hill outdoors on the 115 in near 401 in newcastle. Me and my girlfriend just signed up there and are awaiting our safety course on thursday to shoot, but it is extremely reasonable pricing with knowledgable and friendly staff plus they offer a 24/7 membership option which might be nice for you being out of the area. hopefully this helps, i know its hard to find info on good shooting spots.
