I just bought a new rifle (browning a-bolt, 300 wsm), along with a set of 2 piece Leupold scope mounts. The rear mount is causing problems: it blocks the bolt if it is put on the way it is supposed to go; if I turn it around, it blocks part of the ejection port (the rifle will eject the cartridges fine, but it looks terrible). Has anyone had a similar problem? Could someone recommend a different type of scope mounts for the a-bolt?
