I have a set of 1"rings/mounts that were designed to mount on grooved receivers. I tried both a Leupold VXII and a V-9 Weaver on a 151mb Mossberg, 4-C Savage and a Remington. In all cases, I ran out of windage and the best I could do was 1" right at 25 yards. I love the ring mount combo but I need to replace with something that works. I must assume mine are misaligned or whatever, but I cannot use them on my three rifles. What brand or design do you recommend for grooved receivers?! Thanks in advance, Tom
