For me firearms are like tools, everyone does a specific job, some are better than others but I get them for a reason.
As to what I would like...
An original Wilhelm Brenneke in one of his x64mm cartridges like sharps4590 has....lucky bugger!
As to the big names well that certainly would be a tough one, as to which calibre 450-400 of course, the old queen of the savanna.
Agree whole heartedly with John - "EVERYONE should have a Dorleac", in .275 Rigby HV of course
Yet I'd still like to get a simple BRNO fox in .22Hornet for the grand niece & nephews. They'll be moving onto a property in the near future, they'll need something with a bit more zing!
