CNC Single shot "k" Hornet

Recently given a CNC "K" Hornet anybody had anything to do with these critters? It also has a 410 barrel which I found quite accurate when I chucked a few 45 colt down it. Firing .22 hornet for fire forming to "K" Hornet I was getting around 12mm at 50m ..surprised

Are you sure it's not a 'CBC' ? They are Brazilian manufacturer. Not usually high quality weapons, but you may get the odd one that shoots ok.

Yep it's CBC
