So I can routinely take accurate shots with my Vulcan out to 50 or 60 yds. However out to 75 + yds it's not as consistant. My Prochrono test results have been the same for last 6 months and I check my velocity monthly...no problems there. Recently got bubble level for longer shots and still not very consistant. When installing the bubble level I placed an additional level on the elevation turret to make sure the bubble level was set up correctly. I used a plumb bob, weight on a string hanging from tree limb out to 15 yds. However when I look down the scope with the level on the elevation turret leveled it looks like the reticle is canted.... I'm wondering if the etching of the reticle is bad?? Any suggestions or help from you guys on this? I have a Hawke Sidewinder 6.5 x 20.
