G'Day Fella's,

GG375, I have completed this procedure on both Brno ZKK's and Winchester Mod 70's (Safari Express types in .458 etc).

Though what I did do was to leave all the rear facing flat portions of the action, matte finished.
This included the ejection port, the bolt release and the area in front of it, to minimise the chance of glare!
These areas are also an absolute Pain In The Neck, to polish out By Hand! So it's a Win-Win situation!

As you mention GG375, I also like matte finished receivers. It really looks good on some rifles!

I also leave the inside surfaces of the dovetails on the Brno, matte finished to give some additional purchase for the rings, if utilised.

Sorry no images and I don't know how to post them on here anyway?
Thanks for your help with this Bill!
By the way Bill, I forgot to mention.
If you look at the rear surface of your .404 Jeffery barrel (around the chamber hole), you will see ".404 Jeffery", has been stamped on it!
