In the lesser price range Merkel is one to look at.
Im the upper ranges just about any of the great old european gun makers such as Holland and Holland, Rigby, Purdy Etc Etc will do. Take a look at Cabelas web site. They have a "fine gun room " section that should give you an idea. It's fun to drool over too.
The Classic Big Five is Beautiful.......
I own Two Kreighoff's. Both Shotguns. A k-80 and a k-20. The quality is everything you would expect it to be. I've shot maybe 75 thousand rounds though my k-80 in six years of competition and practice and the triggers are still perfect. It has been serviced by the factory once but it was just a routine cleaning.
I will own a dbl rifle at some point. .470 NE maybe I'm not sure. I don't have a need at the moment.
When you are ready to buy, Contact Kurt Grates @ Great Lakes Sporting Arms in Walled Lake, Michigan. He will give you the best price on these firearms. On occasion you will see them at Cabela's, but this is not the right place to make a purchase of this type.
What do you do with those empty nylon feed bags or dog & cat food bags? Can you say recycle? I use them for target practice for the youngsters. Take your empty shopping bags, stuff them into an empty nylon feed bag. You can also use old clothing or rags, (but put them in the bottom so it doesnt get top heavy). When your bag is full, fold the top over, punch some holes into the top and zip tie the top shut. Paint, draw, paste, or have the kids decorate their new target. Set it out 10 or 20...
