I've had quite a few Ruger Hornets in both the standard(blued sporter), and the heavier 24" laminated stainless versions. All mine have been decent shooters, with a couple being awsome by Hornet standards. Me and my son both currently have a standard Ruger Hornet, and both rifles(with my handloads) will shoot around an inch at 100 yards, which is plenty good enough for the ranges we use a Hornet in.
The most consistantly accurate factory Hornet load I've ever tried is the Winchester 46g HPs. This load has been very accurate in nearly every single rifle, and also a few Contenders that I've tried it in. It'll knock a groundhog flat out to 200 yards, but might be just a tad rough on a pelt. I know it's way to destructive for foxes, but it might do OK on a coyotes hide.
