If you want a shooter, better to get a new rifle.

If you want a vintage gun, and are prepared for the potential problems that may be associated with it and the costs of addressing those problems, there are a lot of interesting old English guns to be found. But be prepared to pay the price to correct anything which may be wrong with them. And be prepared for the unexpected, such as the H&H which blew out a chunk of its barrel. Seems there are quite a few vintage H&H that have done that, and no one seems to know why, and there does not seem to be a way to predict/avoid it.
