I resurrected one for a friend a couple of years ago. I believe it was a 1983 or 84 BBR. Built like a tank they are.
His is a 7mm Rem. mag and it is very very accurate. They have a massive recoil lug, even a bit of glass to bed it. Nice trigger and pretty wood.
My only knock on the gun was the weight, they are not light, not at all.
