HUSKERxdm............. is right on.
Because.............My new Ruger Slab-Sided MKIII .22LR does the very same thing. From the bench, shoots nice, tight groups centered about 1" left at 21 feet. [Rear sight is dovetailed; won't respond to light taps w/my plastic bullet puller.]
This thing appears to be an epidemic!!!! Maybe the Brady Folks have planted moles on the handgun assembly lines. You know....Gun Shoots LEFT!!!
And I just can't bring myself to using Kentucky Windage. Violates all ingrained USMC instincts and learned behaviors.
Maybe NFOA should invest in a community sight-pusher. We could form a tool co-op for bigger ticket items like chronographs, really good spotting scopes, odd-ball caliber reloading dies, canisters of rare powders in large quantities, and.....rear sight pushers. We could call it Andy Allen's Rent-All Shooter Stuff.
