Hi,
I'm interested in buying a new double rifle in a larger calibre probably 470NE or 500NE. I'm not made of money so it would probably be a Merkel, Heym, Chapuis, or maybe a Kreighoff. My question is what are the pros and cons of each of these rifles such as surface finish externally and internally, are any of these rifles prone to a particular problems down the track( parts availability), and general quality differences. I'm open to other suggestions aswell I don't want a wall hanger so to speak I want this to be a working rifle to be used a frequently as time will allow.

I thank you in advance.

Regards,

Keith.
