IMO you can't get any better than an original Type A Mauser Sporter made for the English market. Here is one in 404, 9lbs all up with scope and loaded 3 + 1. Other gunmakers, famous or not, just took the same action, threw a barrel and stock on and attempted to duplicate the Type A Mauser. Some produced some fine sporters but I don't think any were better.

If you duplicated this you will have an ideal BG rifle. I can take some measurements of the barrel contour if you wish.
