got a 10x SS less than a year ago new, after watching them perform well on a couple buddys guns. mounted mine on my SA m1a, w a sadlak mount and badgers. things were goin great! till the last time we went to our 1k range. after some dope gathering and load dev checking it was time for some fun. came up 10 moa and hit 2 bowling pins @ 500yd, up 14 more and hit a steel ram @ 800, up 10 more and missed a steel gong at 1k, but after a nice wind call by my buddy hit the gong w the next 2 shots. 34 moa total, using a lapua scenar / varget load my m1a likes
so... whats the problem ...
dailed the 34 back down, was gonna fire 1 round to recheck my zero, and dangit, the shot went 6'' low at 100yd. fired 5 more, nice group centered 6'' low
anyways , i blew it off, i was going to do a complete tear down and rebed the m1a after this trip anyway.
recently completed the bedding job and was able to shoot the rifle at 100yd only yesterday. groups were nothing special, fired some 175smk loads, that gave me a 1moa group, but 6''high and 3'' right at 100yd. so i dialed 3L and 6 down, and the next group showed up online horizontal, but dropped 8'' from the first group. i rechecked my measurements and click adjustments, and it seems i got 8MOA down when i dialed 6.
i can try this scope on another rifle, in fact a buddy wants a SS, and now im thinkin of putting it on his rifle(a rem788) to see if we have the same problem, before blaming the scope. scoping an m1a can be an exercise in frustration, and i dont want to blame the SS yet, esp when ive seen them pounded w 338 lapuas etc w nps. however ive been over the m1a carefully, and cant find anything loose on the mounts or rings, and it appears ive had the same problem both before and after the bedding job.
anyone got any ideas / things to try? ive tried sighting it on something and dialing up and down, but even my gun cleaning vise doesnt hold everything tight enough for me to draw any real conclusions. i dont have a boresighter, although i guess i can get one.
ty all!
great site

Are you sure you did not get the screws on the rear scope rings too tight? the torque should be 12 to 15 inch lb. ( not foot pounds ) I have made this mistake when not using a inch pound torque wrench. It will cause the reticle to bind and jump when you are twisting the dials. Just a thought

Chris, you should consider carrying a few troque wrenches, a cheaper one and a really good one (not to say cheap ones aren't really good, but they aren't.)

You don't need to spend $1800 on a torque wrench. An impact type snap on is as good as you ever need, even for aircraft maintenance. Honestly just calibrate your elbow and you should be fine.
