After reading up on .223 Rem. balistics, looks like 250 or so yards is about it for coyotes. I have a Stevens 200 camo short on lay-a-way that has a Bushnell 3-9x40 mounted. My question is, will 9x be enough? Plan on trying a little coyote hunting and some varmit hunting so I assume that I'll need a variable power scope. I'm not really looking for scope recommendations (I don't want to open that can of worms) but was wondering what power and obj. dia. would be needed at 250+ yards. Also I was wondering if there is a specific reticle that I should consider. Thank for helping this FNG in advance, Dave
