Gallatin, there are others with much more experience and knowledge than I but I am in the process of building a DR from a CZ and am very happy with the action so far.

I posted some information in the DR section of this Forum (before this section was created) if you are interested.

In summary I started with a Bobwhite 12GA and am making a 470NE. Proofing and regulation is complete (although I still need to solder the spacers). I have shot over 100 full loads through it and it is still tight as a drum. I used a gunsmith to fit the barrels and complete the extractor work and he is very impressed with the strength of the action.

If I had it to do over again I would start with the same action without hesitation.
