GH, welcome. Just a thought, the .375 will do anything you ask of it and the ammo is available everywhere (assuming belted in a magazine rifle). Knowing the UK police it might be more difficult to get bigger stuff unless you can prove you need it. Believe me the travails I have are unbelievable. In November I took my .375 back to UK for case fitting. I obviously had to get a visitors certificate and my friend, a registered firearms dealer, sorted it for me but had to write a letter confirming the gun would be at Hollands for the duration. Last Monday I phoned my friend to get me a visitors certificate as I will be picking up the gun after a range visit to Hollands to bring it back home to Spain on the 11th April. My friend phoned me last Thursday to say the police have refused to give me a certificate as I will be "acquiring" a .375 ??????!!!! My friend advised me that this was nonsense since I own the gun and have a Spanish guia and a EU firearms certificate to prove I owned it before I took it back to the UK. I told him that if the police don´t issue a certificate he can merely re-export the gun to me but I will be billing the police for all transport and insurance costs. It should be sorted next week but just a warning to you. When I took my .470 through London because I was changing airlines and terminals I had to pay a courier 500 quid to carry the gun for me from Terminal 1 to terminal 3 !! (my fault, if I had realised earlier I could have got a visitors cert for the purpose).
