vole Posted March 30, 2010 Report Share Posted March 30, 2010 (edited) Had trouble with a new scope and mounts. Could not get enough elevation to get onto the paper. Was told to put shims under the front mount but was hit with a series of misfires before I could zero again and packed in. My brain tells me that to lift the front of the scope makes the muzzle and the reticule point away from each other so making it shoot lower still. One pw member agreed. 3 folk down the rfd tell me I should be shimming the front too. I was prepared to accept the opinion of the majority until I came across this http://www.youngmans.com/acatalog/Setting_up_your_Scope.html Who is right here? Yours, Confused.

al4x Posted March 30, 2010 Report Share Posted March 30, 2010 (edited) something is fundamentally wrong, is there any difference between the front and rear one as they could be the wrong way round Edited March 30, 2010 by al4x Quote Link to comment Share on other sites More sharing options...
vole Posted March 30, 2010 Author Report Share Posted March 30, 2010 Are they not level? Quote Link to comment Share on other sites More sharing options...
al4x Posted March 30, 2010 Report Share Posted March 30, 2010 doesn't sound like yours are or you would be able to get on paper try assembling again but if level there is no way you should need to shim anything Quote Link to comment Share on other sites More sharing options...
chrispti Posted March 30, 2010 Report Share Posted March 30, 2010 Shim the rear with a piece of old camera negative (cut down to size) Quote Link to comment Share on other sites More sharing options...
albob Posted March 30, 2010 Report Share Posted March 30, 2010 if not enough elevation,then as above,shim the back but,i would swop the scope rings round(they may even not be a matched pair)and try them that way first before shimming,as it is something that is not always needed doing. also was the gun accurate before you got the scope or mounts,as it may have other issues? al Quote Link to comment Share on other sites More sharing options...
Frenchieboy Posted March 30, 2010 Report Share Posted March 30, 2010 Sorry if this sounds a little patronising, it isn't meant to be, but the solution is quite basic and not rocket science! If the rifle is shooting low with the scopes set to their maximum adjustment then you need to put the shim under the scope at the rear mount to raise the rear of the scope up. If however the rifle is shooting high with the scopes on their maximum adjustment then the shim needs to be under the scope on the front mount to raise the front end of the scope. However, it might well be worth trying to change the mounts around first by moving the mount from the front to the back and vice versa, this will sometimes solve the problem. If they really are a long way out you should check the mounts as they might not be a matched pair! Hope that this helps solve the problem mate!

6br Posted March 30, 2010 Report Share Posted March 30, 2010 try swapping the mount round if it shoots the same pack the back mount up with 35mm negative film. I ways lap all my rings so they are in perfect alignment, the last scope I put on a rifle I bore sighted and it and needed no adjustment at 100 yards.

Frenchieboy Posted March 30, 2010 Report Share Posted March 30, 2010 I wasn't aware that it was on a rimfire. However the principal is the same! Quote Link to comment Share on other sites More sharing options...

I swopped round then reversed the mounts even and the last shots I took were well low. Not at all Frenchieboy. The above posts confirm what I thought and that the rear of the scope needed lifting. The last time I used scopes on anything was on a BSA Airsporter potting woodies out of the window. This being 30 years ago. I need to hear this stuff in order to gain experience. These are not novices I am getting the advice off but it just does not make sense.To lift the objective end of a scope results in a lower placed shot in my mind. Now I am clear on it I can sort it. Thanks chaps. Quote Link to comment Share on other sites More sharing options...
wymberley Posted March 30, 2010 Report Share Posted March 30, 2010 Hi, Just a thought because no one has mentioned it; you weren't shooting at a short range just to get it 'on the paper' as it were before moving back to your preferred zero distance by any chance? Cheers Quote Link to comment Share on other sites More sharing options...
vole Posted March 30, 2010 Author Report Share Posted March 30, 2010 50 yards only Wymberley. I was just doing it all wrong. I have had quite a bit of practise zeroing the club rifles but when mine needed adjustment I got a bit lost really. Lifting the back end would have helped instead of the front it seems. Will get my firing pin prob fixed then back on the targets before I go anywhere near a field. Quote Link to comment Share on other sites More sharing options...
albob Posted March 30, 2010 Report Share Posted March 30, 2010 Albob, this is the 1st time I have used the gun. I swopped round then reversed the mounts even and the last shots I took were well low. as you do not know the history of the gun,i would check things carefully. try the things above suggetsed and if no joy,try withou silencer on. when you say low,are they in a group or a line or shotgun style? is the gun new or secondhand? al Quote Link to comment Share on other sites More sharing options...
vole Posted March 31, 2010 Author Report Share Posted March 31, 2010 Second hand Bob. It did not spray the shots around but they ended up crazily low due to me doing the wrong things in a loose group. Will try without the mod as you suggest.
