If you want to shoot for a high average using those expensive shells, wait till they lite. But on second thought; absolutely not, a very bad plan indeed 'cause the first rule of dove shooting is that you NEVER shoot at low birds! So try this plan instead, once you've located that field being used by hoards of wary doves, find yourself a tall dead skeleton of a tree in, or on the edge of that field. Doves gravitate to such dead trees as they have a tendancy to perch and survey the field in advance of feeding. Make yourself a good blind at that tree; and as those little grey buggers fly in to perch, they'll flare their wings and come to a near stop and BOOM! Another good plan for a stand is to find a field with a power line pole in the middle, again as they like to perch on power lines near poles and survey the field. There are also things to avoid while dove shooting; and although I haven't hunted Ontario, I suspose I'd want be wary of critters like bears and moose. Down here in Georgia, my first rule for dove shooting is to NEVER, NEVER set your dove stool down next to a yellow jacket nest; if you do, you can be guaranteed to have a bad day afield. My second rule for dove shooting is to NEVER set your dove stool atop fire ant bed; and my third rule for dove shooting is to make sure you're picking up a dove in those weeds and not a rattle snake. I've found, provided it's not too danged blistering hot, that I can always enjoy a very pleasant day in the dove field provided I observe those three very simple rules. And good luck to ya', as there's no greater sport in the wing shooting world than dove shooting, especially if you just happen to find yourself in the "hot" corner!
