Good day members

The past year or two I read about double rifle builds using side x side shotgun actions. On this forum especially various members build beautiful double rifles on shotgun actions, feedback is great and their builds do not have to stand back comparing to double rifles build by known companies....my opinion naturally...

My question : how acceptable are these builds in the expensive/real double rifle environment , on other forums I noticed remarks like " cheapies, poor man `s double, back yard double" and yet I can not find fault with the craftsmanship of members building these exceptional double rifles on shotgun actions...

Are there specific rules to abide by when engaging such a build? How much "inferior " are such a build in comparison to the double rifles build by companies like Sabatti, Merkel, Westley&Richards , CZ ect?

I really would like to hear your honest opinion in this regards...
