I have an older version of that, in 470 Nitro... however, I feel the 500 is a superior caliber..

WR used to have their USA office one block from my office.. became pretty good friends with the father/son combo... we would go to the local gun range and fire weapons given to them to be sold on-line.. so we checked to make sure they were in working order and how they would group... Was always a good time..got to shoot some incredibly expensive doubles.. in all sorts of calibers.. from the small to the 577Nitro's...

Always felt the prices they charged were way to high which is probalby why they are no longer here.. but, was great fun to go over there during lunch and peek around...
