You didn't pay as close attention to what he wrote as you usually do RR. If you did you would have noted this ("Even with just minute adjustments of the scope, it would make 4-6" impact difference!!!! ) That right there is telling me you have a blown scope. Vortex scopes are pretty good but any scope manufacturer will get a goofy one occasionally. Sounds to me like you have a loose Ret. If just a tiny adjustment to the scope makes a vast 3-6" difference then that's a scope problem not a rifle or loading problem. Return scope or, as RR said, put a known scope on there for testing first to verify what I am almost 100% positive of THEN return scope. Vortex has a good warranty if I remember correctly and supposedly they have excellent customer service.
