10WM Posted June 4, 2011 Report Share Posted June 4, 2011 What hapens when i have reached the end of the ajustments on my scope turrets. Do i Count the clicks then center them and re zero or what? Thanks Not quite sure of the question, In an ideal world the required zero would be in the centre of both up and down and side to side adjustment, but invariably that isn't what happens. If you are miles out as happens sometimes, it may require you to shim the scope or mounts, to bring you back nearer to the ideal. I had a friend who swore by photograph negative as a shim. Hope that's the area the question was aimed at, sorry for the pun. Quote Link to comment Share on other sites More sharing options...
Beretta28g Posted June 4, 2011 Author Report Share Posted June 4, 2011 My question as stated but slightly clearer. Ive run out of verticle ajustment on the scope turrets, its screwed right in. How do i go about getting some more ajustment on the scope turrets? as i now have to aim off as i cant correct the crosshairs enough.

Colster Posted June 4, 2011 Report Share Posted June 4, 2011 Try swapping the mounts over front to back, if that doesn't help then shimming maybe the answer. Quote Link to comment Share on other sites More sharing options...

Okay simple answer, you have to raise the front mount or lower the back mount to give you some mechanically different scope elevation.Ideally this would be to the centre of your up and down adjustment. If the scope adjustments run out you cant do anything more with the scope. so need to alter the mount position physically. (Shim) Depends what rifle its on? I seem to remember 1 thou at the mount is roughly 1 MOA at 100 yds. An air rifle would obviously be lots different 4 thou would be 1" at 25 yards. so you could roughly work out your required shim size. but it does depend on the centres of the mounts? Best wishes with your job. Quote Link to comment Share on other sites More sharing options...

Be carefull on the latter meathod as too much or too tight a screwdown will damage the tube. Old negatives, shims or even wet and dry paper have been used sucsessfully and you dont need very much. its quite likely there is something to sort here like a barrel droop issue or a faulty scope / mount problem, look into that first Quote Link to comment Share on other sites More sharing options...
Beretta28g Posted June 4, 2011 Author Report Share Posted June 4, 2011 The scope is a Hawke Eclipse 3-9-50 IR on a .22LR zero'd at 60 Yards. So I ve gotta shim, but with what? Quote Link to comment Share on other sites More sharing options...

ste12b Posted June 5, 2011 Report Share Posted June 5, 2011 Try this. It may help. Use a piece of negative (from film camera) as a shim. Quote Link to comment Share on other sites More sharing options...
bigstevouk Posted June 5, 2011 Report Share Posted June 5, 2011 Has it got a moderator on? If so check its all tight, you could try zeroing with it off and see if that makes any difference... Quote Link to comment Share on other sites More sharing options...
cooter Posted June 5, 2011 Report Share Posted June 5, 2011 The scope is a Hawke Eclipse 3-9-50 IR on a .22LR zero'd at 60 Yards. So I ve gotta shim, but with what? I use folded aluminium foil, as in kitchen foil, and have done for years wihtout any problems. If you have to shim then add a little extra, to try and bring the adjustment nearer to the middle of the range, as some scope are a little suspect when they are at the extremes of their adjustment, and they fail to hold zero. I have only had one set of mounts which could not be made to provide enough adjustment, until I tapped the recoil lug out, then it was all good.
