Wonderful job.
I just got a Brno 600 in .270 - same rifle as you have above. I got it with the idea of rebarreling it to 7x57mm at some stage, but I have slowed down on that since it shoots fine and the bore is excellent...
You have done a very good job of reworking that CZ stock to look like the Brno original.

Do you care to share your stock finish recipe?
