No gun at £2k is good value for money

I'd also be wary of taking a gun of that value out into the field hunting, so it may be your budget, but for your use I'd probably dial it back a bit.

Think what you like/dislike about your current gun and then let us know what you want - the brief is very large as it is and I'd be leaning towards a Red Wolf in walnut or a Wolverine R which are both awesome and no heavier than what you have
