I have heard about wrecking cases on the 22 Hornet. However I have had a couple and reloaded for them and just never had any trouble with that. Shells for the Hornet are not cheap but if you load for it, its a cheap caliber to shoot. I really like the hornet and used it for deer hunting for a while. Until I found out that it was not a legal caliber in our state. Its a good little varmit caliber out to 200 yards. I am going to send in one of my NEF rifles for a Hornet barrel soon. Love those NEF's.
