Isn't it just typical of the plod bullshit.
Oooh no,you can't have a .338LM (which can shoot a 225 grain bullet) 'cos it's too much gun......but we are okay with a 30-338LM firing a 240gr bullet!!
I remember years ago being allowed a 22lr for rabbit shooting, and later on I asked to change it for a 17hmr to be told that "I could not have of those because they can penetrate body armour" Really? So the .308 that I also have can't do that then?
