I wouldn't go the .22 route myself; IMHO, shooting a rimfire creates a mental hurdle when it comes to moving up to a centerfire. If you focus and concentrate on each step that's necessary to make a good shot, from finding your natural point of aim to the follow through after the shot, when shooting from a solid position; your brain won't be able to consider the discomfort it associates with firing, unless you allow your concentration to break. Force yourself to relax prior to the shot. Wear hearing protection when you shoot, as the flinch could be noise rather than recoil related. Take steps to ensure the rifle can't hurt you when you shoot. It should fit, and if it needs a pad to be tolerable, get one installed. If the scope is behind the cocking piece of the bolt, and the stock fits you, you might be scared of getting tagged, so move it forward. Shooting with a sling from a supported position will keep the butt tight to your shoulder, rather than allow it to take a run at you. Some years ago I let a fellow, who I thought was an experienced rifleman, but wasn't, fire my .416 Rigby. Before I could stop him, at the moment he let it off I could see daylight between the butt and his shoulder, and it hit him like a fright train. I doubt if he could shoot a Hornet without flinching now.
