Fred- please do some research and investigation into the power a .22 pellet rifle puts out before you consider shooting at a fox or coyote. I'd also check your local laws to see what permits and licenses you need to hunt either. You could get yourself in trouble if you come across a game warden before taking a single shot. Right over the boarder from you in PA, you cannot hunt animals that large with a pellet gun and you cannot take a fox with a standard hunting license, you need an additional furbearer license. I imagine MD is similar, but that's just a guess. Despite foxes and coyotes being despised by farmers, they still deserve to be dispatched humanely and not wounded to suffer and die over a period of days or weeks. In that vein, my advice is to spend 400 bucks on a Remington 22-250 and save the pellets for the squirrels and pigeons.
