cohntr6 Report post Posted July 4, 2018 Hello and Happy 4th!! Got a new rig I'm trying to get zeroed for 100 yards. Here's the details: Larue 20 MOA bases Leupold Mark 5 scope 5-25x56 (.1 MIL turrets) I mounted and leveled the base/scope Bore sighted in the house (things looked good) At the range: Scope was at 0 on the dial and bullets hit 3" high and 3" left at 25 yards. Ok Corrected the windage (verifed with a shot) Moved target to 100 yards (and assumed point of impact would be the same) Boy was I wrong!! Next couple shots went 3 FEET high. Let the barrel cool (as much as possible when it is 90 degrees outside) Dialed scope down (.5 mil is all it will go) Shot high at 100 Held 3 Mils of hold over (above the center zero cross hair) Shot and hit paper (high of course) WHAT AM I MISSING? Thanks for any help! Again, remember I cant dial down in elevetion. Also, I decided to shoot at 767 yards and all I had to do was hold 1.5 mils to hit the target or I would shoot high.

firstcoueswas80 Report post Posted July 4, 2018 Is the elevation turret bottomed out, or are you hitting a zero stop? 1 Share this post Link to post Share on other sites
Red Rabbit Report post Posted July 4, 2018 If you could only go down 0.5mil, I bet it is the zero stop like Casey mentioned. Did you push in the button on the elevation dial when trying to go lower? 1 Share this post Link to post Share on other sites
10Turkeys Report post Posted July 4, 2018 Usually when something like that happens, there is something loose somewhere, check to see if everything is tight. 1 Share this post Link to post Share on other sites
win71 Report post Posted July 4, 2018 It is your 20 MOA base or a base problem. Your scope is higher in the rear than the front. Seen this on old Ruger-77s when rings reversed 2 Share this post Link to post Share on other sites
dcshorthairs Report post Posted July 4, 2018 It is your 20 MOA base or a base problem. Your scope is higher in the rear than the front. Seen this on old Ruger-77s when rings reversed Yep. Pull that 20MOA base off and throw on a flat base. This is of course you are bottomed out on your elevation dial. I had a rifle that I had to put only flat bases on for this reason Share this post Link to post Share on other sites
lancetkenyon Report post Posted July 4, 2018 Betting you need to adjust your zero stop. No reason with a 20MOA base, you should not be able to zero the scope. 1 Share this post Link to post Share on other sites
cohntr6 Report post Posted July 6, 2018 Yep that was it. Dialed to 5 mils, I unscrewed the elevation cap, reset the cap to zero. Went to the range and I was almost dead on at 100. Just has a couple clicks up and right and I was perfect. Thanks All!! Jeff 1 Share this post Link to post Share on other sites
