If they told you that they haven't been able to get any from BSA they are lying. I run an airgun shop in Devon, and on Monday I ordered myself a .177 Hornet as I am sponsoring myself to compete in HFT. It arrived from BSA on Wednesday.
If you want to come up to Quarry you can share my Hornet, I'm afraid I don't have another one in stock at the moment so I can't bring you a spare up though.
