That's the first double rifle I've seen let alone shoot. The recoil for me was not what I expected. The rifle weighed around 11-12 lbs according to the owner.
Ingwe,agree on the .416's those are just too much for me. The only .458 I've shot was the Win mag version and it was enough.
Rev,we are looking at either a Merkel or a Sabatti .470 right now. Most likely a Sabatti as they are a little cheaper,but we will see,there is no hurry.
