I find the old Hornet to be a very useful old cartridge and a fine crow killer. Although it does not possess internet accuracy, my little Ruger will consistently shoot 5 shot groups somewhere around an inch or very slightly larger at 100 yards with 45 grain pills. It took a few tries to find the handload that it likes and the brass is very thin but it is worth the effort.
I don't use it to shoot varmints more than 100 to 150 yards, but it is neighbor friendly as it has a bit less noise than a 16" battleship gun (which I would gladly use on crows if I had one). It fits in well between the .22 LR and the .223.
