At present I'm using a Ruger Blk hawk Bisley Hunter in 44 Mag with a 2X Leo. Like it , shoots great , it will be a little barrel heavy if your not used to a scope. Personally , I wouldn't go any bigger than a 4X as far as scope goes , the more the power the more it will magnify your shakes and the less field of view it will have. I think a 2x is ideal. IMO........regards , irold
