mintbore 15 Posted July 31, 2013 I must be doing something wrong. The last 3 installs would not get on paper no matter how much adjustment...maxxed out windage, elevation or both. I end up having to use Burris rings with the inserts (and twice that didn't give enough adjustment), or having to shim the SH*T out of it. The bases are tight, the rings are torqued evenly...but still every install turns epic. Any gunsmith tips? Thanks Quote Share this post Link to post Share on other sites
djg0770 481 Posted July 31, 2013 What brand of scope? Quote Share this post Link to post Share on other sites
Vlad G 345 Posted July 31, 2013 What gun, what scope bases, what scope rings, what scope, what scope ring height? Quote Share this post Link to post Share on other sites
Worn_Holster 2 Posted August 1, 2013 I like to lay the gun down stationary and set the crosshairs on an object that stands out 75 to 100 yards away. Without moving the gun, I then look through the bore to see if that object appears close to what I see through the scope under the crosshairs. It is a sanity check, and only works on firearms that you can easily view down the bore. It always gets me on paper at 50 yards. Quote Share this post Link to post Share on other sites

Walt of Destiny 412 Posted August 1, 2013 While the bore sighter is the way to do it... that is beyond the problem he is having.........! Wondering if we will hear back !! Yes I know, but I believe that initial fitting is the issue. If he looks through the scope BEFORE torquing everything down he can see where he is off and move it around manually until he sees something. I'll bet it's an elevation issue. The ring heights are incorrect for the application. And if in frustration he cranked the adjusters too far, it's toast. Without his active participation in his resolution, we may never know...

mintbore 15 Posted August 5, 2013 Silly question but are you sure you are using the correct diameter rings with the correct diameter scope? Also are you matching the scope to the round being fired? I must say that I have only twice had a scope install (on holes drilled by others) that required minor shimming. Sometimes I do find that the selection of the mounting point is not optimal and/or off center axis. To that point check the mounting holes for proper location for both elevation and axial location. If you need to excessively shim for windage I bet you that the hole are off axis Sorry for the delay...back from a business trip...Here are the combos and guns: Mossberg 144...1" ring base combo made for this rifle. Swift 3x9940 scope Colt AR...PEPR mount, Nikon 4x12 SF Monarch Used bore sighter for both, thats how I found I was so off Both off by about 16" at about 30 feet (longest I could go from the garage to the back wall) Quote Share this post Link to post Share on other sites
Poisontail 0 Posted August 5, 2013 Did you buy the scope ring alignment kit? Quote Share this post Link to post Share on other sites
tony357 386 Posted August 5, 2013 Have you shot the gun to see point of impact, maybe the bore sight is off.. Quote Share this post Link to post Share on other sites
Vlad G 345 Posted August 5, 2013 Make sure that your bases are mounted square. Don't tighten one side then the other, for example on the PEPR mount, finger tighten each bolt and then go one turn at a time on each bolt to make sure it is evenly tighten. Are you off the paper horizontally or vertically? Quote Share this post Link to post Share on other sites
Worn_Holster 2 Posted August 5, 2013 Looking down the bore worked for me at Cherry Hill on Friday. With a bolt gun, it's pretty easy to see just where the bullets will go! 100yds from a benchrest, Prvi Partizan 196gr FMJBT M75 sniper ammo from Widener's.

Since both are unitized mount/rings...that may be it...I'll remount using a 1/4" torque wrench Thanks PS- Awesome Mauser! Quote Share this post Link to post Share on other sites
Sht 3 Posted August 12, 2013 Bore sighting should get you on paper or at least close. If your range setup allows for it, use the back side of Xmas wrapping pared to cover as much of the back stop as possible. Quote Share this post Link to post Share on other sites
Sixtytwo327 14 Posted August 12, 2013 You can try this: http://www.midwayusa.com/product/453687/wheeler-engineering-scope-mounting-kit-1 I have one; not quite Snap-On quality, but good for amateurs, and it's a nice addition to your toolbox. Even with one-piece mounts, the torque wrench and lapping components might help. Quote Share this post Link to post Share on other sites
