Wildfowler12 Posted November 17, 2012 Report Share Posted November 17, 2012 Evening all, I bought a new springer this week (Stoeger X20 Suppressor .177) and a 3-9x40 scope. Problem is that it's shooting very low, about 4inches even after the elevation has been adjusted all the way! I thought the scope might have been mounted wrong, so I took it off and started again but i'm getting the same results. I read that you can get 'barrel droop' but I don't think this is the problem. Any suggestions would be appriciated, it's grouping fairly tight, and the windage is bob on, it's just the elevation :( Quote Link to comment Share on other sites More sharing options...
Tod Posted November 17, 2012 Report Share Posted November 17, 2012 Had the same problem on a rapid i had, just packed the front mount with some thin rubber to raise it slightly and it sorted it. Quote Link to comment Share on other sites More sharing options...
bunybasher1000 Posted November 17, 2012 Report Share Posted November 17, 2012 Try swoping mounts back to front.you could also shim the mount. Quote Link to comment Share on other sites More sharing options...
evo Posted November 17, 2012 Report Share Posted November 17, 2012 seems a little strange considering its a new gun, :hmm: Quote Link to comment Share on other sites More sharing options...
la bala Posted November 17, 2012 Report Share Posted November 17, 2012 turn your elevation *** all the way to bottom, now count your clicks all the way back to top, half that figure and turn it down that amount of clicks, now try for zero.

FalconFN Posted November 17, 2012 Report Share Posted November 17, 2012 As said, swap the mounts around first and if that dosent work shim the rear mount with something like a piece of 35mm film. Quote Link to comment Share on other sites More sharing options...
Scottoj18 Posted November 17, 2012 Report Share Posted November 17, 2012 (edited) i had the same thing with a bsa lightning didnt have a clue what it was till i looked down the barrel and could only see a half moon and the end. bent barrel i just cocked it and bent the barrel the otherway works well... this would be a bit strange on a new gun .... . also try shooting with open sights to confirm if its the gun or the scope Edited November 17, 2012 by Scottoj18 Quote Link to comment Share on other sites More sharing options...
NIGHT SEARCHER Posted November 17, 2012 Report Share Posted November 17, 2012 Has Falcon FN said . Its a very common problem the 35 mm film works well. You can get Scopes that are designed for air rifles and will zero at 30 yds but scopes designed for firearms zero at more like 100 yds.

Wildfowler12 Posted November 17, 2012 Author Report Share Posted November 17, 2012 Thanks for the advice guys, I'll swap the mounts and try again. It seems wrong to have to use shims, given that it is the stoeger scope that comes with the gun as a package?! Hopefully I've not bought a 'dud-un' :( Quote Link to comment Share on other sites More sharing options...
timmytree Posted November 18, 2012 Report Share Posted November 18, 2012 Had the same problem on a rapid i had, just packed the front mount with some thin rubber to raise it slightly and it sorted it. I don't think that will help, packing the front mounts will make the problem worse surely? As suggested elsewhere, swap the mounts and see if that helps, you could try a set of adjustable mounts but that means more money, or take the outfit back and tell them the problem and ask them to sort it out.

Falcon. I agree .....Shim the rear mount. Quote Link to comment Share on other sites More sharing options...
kent Posted November 18, 2012 Report Share Posted November 18, 2012 It can often be a windage jamb. set the scope to windage central posision then forget were the verical placement is now just zero on elivation, then and only then set the windage. To be fair some scopes can just be plain faulty and also some guns can suffer droop or alignment issues genrally. so the next step is try a borrowed yet proven scope. If the 2nd proven scope dont work its likely to be a gun fault. Mounts are easy to alighn visually with a straight length of the appropriate bar diameter just tighten in the mounts its more likely to be off to one side than up or down as sometimes people have one claw foot reversed or it aint seating in the groove well. If your way off on elivation you will need too much packing and it likely as not will deform the scope body tube on tightening Quote Link to comment Share on other sites More sharing options...

If you pack he rear mount you are forcing the rear up, with will lower the aim point. The OP wants to raise the aim point, so you must shim the front mount. Seeing as it is a brand new gun I would do what the OP suggests, take it back and say "You sort it!" Quote Link to comment Share on other sites More sharing options...

Dekers Posted November 18, 2012 Report Share Posted November 18, 2012 By all means asking is good, and may be useful, but frankly, if this is a new setup then just take it back as a few have suggested! Quote Link to comment Share on other sites More sharing options...

chrispti Posted November 18, 2012 Report Share Posted November 18, 2012 As said, swap the mounts around first and if that dosent work shim the rear mount with something like a piece of 35mm film. Agreed, i cut down a piece of camera film/ negative film, whatever you call it. Center the elevation dial, shim the rear to bring the center of the crosshair down onto the impact point. Tighten up the mounts and zero the scope. Quote Link to comment Share on other sites More sharing options...
secretagentmole Posted November 18, 2012 Report Share Posted November 18, 2012 Sorry pre coffee statement! Apologies! Yes it needs to go lower, so it is the rear. But I would be taking it back! As an incidental zero the scope first (click it all the way from one extreme to the other), halve it and click back, do this for elevation and horizontal. See if that makes any difference, if it does not take it back. Also what distance are you attempting to zero at? Quote Link to comment Share on other sites More sharing options...
Jega Posted November 18, 2012 Report Share Posted November 18, 2012 (edited) :good: How and where and why do people come up with this stuff? Not sure where they get it from mate .its quite a simple job to re-parallax most scopes to the required range,just about every scope i've owned (and thats quite a lot) has required re-parallaxing to air rifle range which in my case is parallax to about 28yds for a clear picture ,this gives me a really good 35yd zero which in turn gives me a nice crisp picture from about 15 to 45 yds which is where it just starts to go out of crisp focus this also comes in handy for a rough 45yd distance guide also means i generally only have to use 1 mildot .As i dont go much above 45yds on live quarry with an air rifle this suits me fine.

Capital Bee Posted November 18, 2012 Report Share Posted November 18, 2012 How do you re-parallax a scope? I've a couple here that I could do with taking about 15mtrs off of current. Quote Link to comment Share on other sites More sharing options...
Jega Posted November 18, 2012 Report Share Posted November 18, 2012 O.K so assuming your scope hasnt got parallax adjustment its a straight forward simple job to adjust it to suit your needs. First remove the objective lens (large end) cover, this is screwed on and once removed will reveal the lens carrier assembley which is where the parallax adjustment takes place,it takes very little movement to make the adjustments so try a little at a time by screwing the lens carrier in or out as needed.
