Hello all, i have a Tasco Silver Antler 3-9X scope, i mounted it on my Winchester XPR 308 bolt action, with Weaver extra high scope rings, the scope was shooting 6 feet straight up, i used a laser bore sighter for 50 yards, apparently it wasnt any good LMAO, any advice or tips
 
Pull the bolt. Lock the rifle down so it won't move. Look through the bore and center on your target. Look through scope, and move crosshairs to center of your target. Replace bolt anf fire a round. Should get you on paper, anyway.

Thanks, I have to get to the range soon and try that, the range is 100 meters, any advise on using used scopes? im goign to put a Viper 3-9X on her now, the silver antler is being boxed up lol
 
Are the bases correct? i.e. the correct bases. Pretty hard for a scope to result in hits six feet off, all by itself.

You may have the incorrect scope ring height. Mount the scope as low as you can get. Be sure the rifle is level. Lay the scope in the rings. You should see no light leaking under the scope between the rings and level the scope in the rings to match the level of the rifle. Assemble the top straps of the rings taking extra care to tighten the screws equally until just snug and no more. Re-check your level and be sure the scope is square with the rifle. This when to set your eye relief. Once you're comfortable with that so you can see through the scope without "climbing" up on it or needing to adjust your head to get a proper sight picture,gently start tightening the mounting screws to equal torque using a cross-tightening pattern. Be sure you don't crush the scope tube. A torque screw driver is your best friend. If you're still having trouble,check out www.youtube.com/larrypotterfield. He's the Grand Master of gunsmithing.

straight from the factory, winchester ones, but i think the rings were too high, i bottomed the scope out and it still was way too high, links to info on scope below, going to see if i have luck with the same height of rigns and Vortex Viper 3-9X lol

I will take a look, at his video, i believe I have before, and I believe I had very little clearance between the rifle and the scope, too little i believe
 
Height of the scope - low rings, extra high rings, shouldn't result in the rifle shooting 6 feet high. A scope mounted on an AR-15 is much higher above the bore axis, yet there are no zeroing problems.
I was wondering if the scope bases were incorrect - if the rifle is shooting way too high, the rear base could be too high, or the front base too low. Or rings of different heights.
Then again, the scope might be grossly defective.

I just looked at the bases and they are exactly the same, ill post a few pictures soon, the scope probally was trash
 
By the same do you mean that they have the same part number?
Or are they the same height if a straight edge is laid along them?
Are the receiver ring and rear bridge of the rifle exactly the same diameter, or is the rear bridge lower than the receiver ring?

Same part number and save level and sight plain, they are the same front and rear, the reciever is a round one and it is the equal dimensions
 
OK, I checked Winchester's website and in the photo, it looked as if the rear base is thicker than the front.
 
Figured it out, that is for the help gang, it was the el cheapo scope.... Got a vortex viper 3-9x40 on her now, all good, on paper now, and need more ammo
