Accuracy of a Puma 92 in 454/45?

[Mattole]

I am considering getting a .454/45 Puma 92, and am wondering what kind of accuracy one can expect at 50 and 100 yards (with good sights or a scope), with ammo that the gun likes and a good shooter behind the wheel. Anybody tried this gun for longer shots, say 200 yards? Thanks.

I recently bought one and am still developing loads. I haven't really tried shooting groups but at 40-50 yards have no problem hitting a plastic 20 ounce bottle with open sights (hi-viz). I don't really like the factory sights so I will more than likely replace them or scope the rifle. I've only shot .454's through it so I have no idea how it will do with 45 colts.
