I have a r-1, 30-06 with the 20" barrel and love it!! It has a leupold 3x9 vxii. It shoots much better than my BAR. I recently ordered a 300 mag with the 20" barrel, and understand I will be losing some velocity, but love the shoerter barrel. The question I have about this new rifle is a friend liked my r-1 and got one for himself, with a ziess scope but could not it to site in using leupold mounts. I don't know if the ziess has less adjustment than the the leupold or if I am going to have a problem with my new gun if I put a ziess scope on it. I did a search and did not come up with a answer, although phenom101 uses QR rings with his and likes them.
Any help or suggestions would be appreciated.
