Would love to own a double in 470 or 500 but could not afford one, however I got a good deal on an early Ruger m77 mk2 in 416 Rigby. I brought it to Griffen & Howe who installed their hooded front sight, shortened the stock forend, and sodered a half barrel band for the sling attachment. After the scope made a good cut over my eye from recoil I had Mag-na-port put their brake on he barrel. This cut the recoil to where I can shoot it from the bench without getting bashed in the head. Put 3 of Federals 400gr solids inside an inch at 100yds. This rifle and my FA`s 454 were the only 2 guns I took to Africa and the 416 accounted for most of the game I hunted. Great gun...
