This past week I attended an LE M-14 Instructor Course. I had only heard of the problem that I was about to experience for the first time in all the years I have been shooting. So wanted to know if anyone else has expierienced the same problem in the past and what did you do about it.
In the military we always shot competition with Iron Sights so did not have this problem there. In the LE SWAT Sniper world I had never seen it happen. Only heard of it!
So, the M-14 Course was a three day course. On the second day we went to a local military facility to shoot from 100 to 500 yards.
Of course as usual my Springfield M1-A National Match performed flawlessly. However after completing the 500 yard line firing we returned to the 100 yard to readjust and confirm our 100 yard zero and dope on the rifle! Well that is when it happened. I have an older Springfield 10X 30mm Tube Scope on it. It had not been used for some 10 years at the begining of this school. Long story short. It would not return Down to the 100 yard zero. It was shooting at least 5 inches high. I dialed 5 MOA Down on the Elevation to attempt to return to the original 100 yard zero without results! The Reticle was stuck. On the following day after removing the scope and completing the course with the iron sights. I took the scope, ran the Elevation adjustment up and down and tapped the turret with a small nylon hammer. Figured I had nothing to loose. It began tracking normaly at that point and still is seemingly working fine today since I have not had time to check it on the range yet. I have heard it was probably a result of not being adjusted or moved for the long period of time? Wondered if anyone else had experienced this since as I advised, I had heard of it, but never had experienced it. Looking for experience and if I can now expect the scope to be OK after the Tap and Working the Adjustment?
