I recently picked up a Redfield 3-9x40 to mount on my 581 series all weather Ranch in .223 cal. I used the factory Ruger mounts that came with the rifle & noticed that in order to get a full picture at 9x in needed to slide it back on the mounts so the rear ring is only 1/8" to 3/16" from the turrets. My question is will this hurt anything because the scope isn't centered on the mounts? Everything seems pretty tight & secure when mounted. Thanks for any feed back.
