I had a similar problem with parallax and called and they paid shipping to and from and confirmed that there was an issue and repaired it. Had it back in my hands in 10 days....
My last elk was a cow shot at 167 Yds with Berger OTM (opened end a little with drill bit) in a 338 Edge at 2825 fps with estimated force of 4720 ft pds. Elk flipped backwards and hit the ground - never to move again. Pretty much liquafied internal organs.
