Okay,
Sο many years ago mу ex-father іn law bουght mе a scope fοr mу .30-06…I gοt іt mounted аt a local gun dealer аnd wеnt tο sight іt іn. Being thаt mу father іn law wаѕ аn avid hunter I felt аt thе time thаt іt wаѕ “Mе″ thаt wаѕ аll over thе paper. Wе wеnt hunting аnd I couldn’t hit thе broad side οf a barn wіth thіѕ thing. Well, іt’s bееn рυt away fοr many years lіkе I ѕаіd аnd I recently bουght a bore sight, magnetic one thаt goes οn thе еnd οf thе barrel, аnd sighted іt іn lіkе thеу dеѕсrіbеd аt thе gun store. Whеn I wеnt tο thе range I couldn’t even hit paper аt 25 yards іn a vice! I later removed thе scope аnd took іt out οf thе vice аnd сουld hit thе paper wіth open sites οn thе gun. Whаt gives? Dο уου thіnk thеrе іѕ a chance thе gun store thаt mounted іt didn’t really care аbουt doing a gοοd job bесаυѕе I didn’t bυу thе scope thеrе? It’s lіkе a $300.00 Cabela’s scope аlѕο! It’s never bееn abused οr smacked hard οn anything! Oh, аnd іf I wеrе tο try аnd mаkе adjustments tο gеt іt οn paper frοm іt’s “WAY HIGH LEFT” thе scope іѕ tapped out аnd nο more adjustments саn bе mаdе.
it might be your mounts weren’t tight. Take it to a gun smith, he’ll help you if he is worth his salt. What brand is the scope? You might try having it sent back to the manufacturer. They might be able to repair it if it is the scope. It might be the receiver wasn’t drilled and tapped right either.
we bought a scope from cabelas last year, about 450$ and we let them sight it in since it was “free” total BS, we couldnt hit a can 5 feet in front of us, so we took it to a different shop and let them sight it in for us, paid like 10 dollars but it was alright afterwards. We dont buy those bore sights from the store, they dont work to well either. take it to academy, or a place that sells guns or a hunting store and ask them to sight it for you, the most they’ll charge is probably 10 dollars or so, but its worth it. Id rather hit my target, then shoot someone in the leg.
Your description makes it sound as if the scope was bad from the start. It happens even to the best of scopes that one or two will get out of the factory defective.
One thing I would try is to center the scope and then put it back in the rings and see if sighting it in is any better. If it simply will not hold or can’t be sighted in, then the scope probably has a manufacturing defect.
This blog touches on the subject of centering a scope and using adjustable scope mounts :http://www. pyramydair. com/blog/2006/01/adjustable-scope-mounts. html I know it is in reference to pneumatic arms but still applies to firearms.
I can not believe that anyone would pay a box store and allow the guy that is the gunsmith this week and that cleaned toilets last week mount and bore sight their scope. It is not that hard. All of the screws must be tight. You don’t need a bore sighting tool for a bolt action rifle or any one that you can see through the barrel. We normally bore sight our rifles at the kitchen table. Mount the sight base. Make sure the screws are tight. You can purchase the Wheeler FAT wrench for $50 or less and it is well worth it if you have a rifle. Mount the rings on the base and sit the scope in the rings. Tighten the rings to the base and tighten the rings onto the scope making sure the the cross hairs and turrets are oriented correctly. Remove the bolt from the rifle. Prop the rifle on something solid and sight through the barrel and find an object through the center of the barrel about 25-50 yds away. Without moving the rifle, adjust the turrets on the scope so that the cross hairs line up with the object that you saw through the barrel. At this point it is bore sighted. It is not sighted in. This should get you on paper. If you are a decent shot, shoot one shot at a target from 25 yds. Adjust the scope so that the bullet would impact your POA. Move to 50 yds and try another shot. Again adjust your turrets. Move the target to 100 yds and shoot and see what you have. You will probably have to make another adjustment. Bore sighting most probably will not get you on paper at 100 yds. It sounds like your scope base or rings are loose. My son did have a brand new $300 scope that was defective and would not hold zero.
Maybe it’s the scope, but a poor mounting job could also be the problem. In either case, you need expert help.
You may have damaged it by cranking it all in one direction. You need the scope in a central neutral position as far as the crosshairs go.
It still sounds bad. The rings may have been to tight and damaged the scope. Only a gun person or gunsmith can help you.
Follow the instructions Mack9 gave you. If you run out of adjustment,you must put shims in the ring. remove ring screws and lift scope place shim on ring replace scope restart bore sighting use as many shims as you need to get near poa make final adjustment with scope turrets. Brass shims are most used. Make shims from beer cans they will do the job,just cut smaller than ring size to fit[roundly] on the bottom ring. That’s what they will do at a gun shop. I do what Mack9 does,word for word.
A $300 Cabela’s scope?
The only name to trust in telescopic rifle sights is LEUPOLD.
I think that the scope was defective from the start and more than that, the gun dealer mounted it wrong (it happens all the time in my state). Leupold is not the only way to go. There are other reliable manufacturers as well (check out the source)
