Fine double rifles in .303 British are rare and pricey, anything decent will be more than 20K now and they are also rather heavy for the power you have "on tap".
I have has experience with only 3 in some 50 years of this insanity; the first a mint Daniel Fraser, cased with goodies which I could have bought for $4000.00, a gorgeous William Evans I could have had for $7500.00 and a Rigby with a D&Ted top rib, sob, which a local treid to suck me into paying 20K for.
To me, a 9.3x74R is a MUCH better choice in a user DR for North America and these are easily found locally at "fairly" reasonable prices; I was offered a Merkel 141 about two years ago for $3800.00. This is the way to go if you really want a DR for NA shooting and the Kreighoffs I have handled plus the Merkels are pretty decent for the cost.
