Blazeone:

I have the same rifle as you in .470 NE. Sabatti apparently uses the same frame for all of its big caliber doubles and as the bore gets bigger the guns get lighter. My .470 balances well but at 9 lb 9 ounces is a little light for caliber. I chose it over the .500 NE partly because of the balance and because at 9 lb 6 ounces I thought the latter would be way too light and hit too hard at both ends. I also like the .470 as the time-proven best all around African caliber. I think elephants are the only reason to go bigger and a good argument for a .577. I don't like the hard factory recoil pad and intend to replace it at some point. Length of pull seems right for me ( I am 6'1") and gun swings and comes to shoulder, with sights lining right up, very naturally.

I haven't shot mine much and this far only at the range, but when I have it has been accurate enough at 50 yards which is what I consider double rifle/dangerous game range. At their price point these rifles are bound to involve compromises but I think they offer good value for the money, with proper (non-dremel) regulation of course.

All the best.
