I bought a Buckridge 1.5-4.5x32 and mounted it on my T/C Contender 445 SuperMag.  It would group 2-3 shots then the poi would change and group 2-3 shots and poi changed again.  If this scope can not handle 445sm loads, how is it supposed to hold up to shotgun recoil.  Complete junk, will never buy again!!!!
