THANKS for responses guys!

Xausa, I thought I would post some more pics on the subject of the .318 VS .323 JR for this drilling. Posted chamber markings and rounds I have presently. I have also fired 8 of these,so I hope they are right! box does not have these measurements listed anywhere. Any comments appreciated.

Also posting pics of my scope mount uppers that I believe to be Krieghoff. These are little works of art all by themselves! Also the scope I would like to mount in these. All comments appreciated! Kevin.
