Spent all yesterday afternoon mounting and sighting in the neighbors Rem. 770 .308. Replaced the Package scope that went out in 4 shots with a Centerpoint 4X16. They come with their own rings. Bore sighting and shots from 25 yds maxed out the elevation and left it at 14" low. This will equate to around 10" at 100 yards.

So obvious solution is to shim the scope. 2 possible fixes are:

Shim the base (rear)
Shim the ring (rear)

Personnaly I perfer to shim the ring first. The scope on my Rem 700 is shimmed on the rear ring and has been for about 7 years and still holds sub .5" groups with hunting loads.

I use aluminum cans, take your pick, Beer (any brand will do), Soda, I used Mountain Dew as it was the first one I picked out of the recycle barrel. I cut the top and bottom off with avaition shears using the side metal. I washed the metal and sprayed it down with brake cleaner and wiped good. I then cut strips to match the ring width and length to go UNDER THE SCOPE, BUT NOT ON THE SIDES. For this application I used 2 strips.

On remounting the scope, bore sighting and re-firing at the 25 HAD PLENTY OF ELEVATION. Moved back to the 75 and had to COME DOWN ABOUT 32 CLICKS to get it centered. Worked great.....again.

Note: If your prefer to shim the base, which I have, May I suggest to use a piece of Old Measuring Tape. The contour is just about right to fit the curvature of the barrel, and even is the mounting surface is flat it will flatten out fine. Just drill holes. Only problem with base shims is SOMETIMES the screws with the origional base will not be long enough and you will have to obtain new ones.

Thanks Bucky, and Greyhawk for the comments on tape. There is always a solution to every problem (more than one) without spending time and money. thats what I like about this forum, experienced people that give sound advice THAT WORKS. Thanks again guys........

Oh, and the reason I dont use beer cans is.....I only drink mine in BOTTLES, the glass is to thick.......

Two more scope projects going. Now have a 32X target scope for the 7XVH .223. Will replace the 24X. The 24X I will put on the old Marlin Model 80 that has mis-aligned base holes. I also obtained a set of Millet Adjustable rings to correct the alignment problem on the .22. Deer season is down for about 10 days until Alternative Method in the middle of the month. So have some time to kill at the work bench.

Wow...a 32 power scope. Are you shooting critters with that or reading the WSJ at a 100yds. I have learned I can't steady high power scopes in the field. Once the magnification hits 12x I need a bench and sand bags. More power to you SWO1. Pun intended.

Its a variable...really wanted a fixed but got this one for $70 new at the gun show yesterday, its a Simmons like my 24X. Just poken holes in paper, but like you if hunting usually dial em down to about 4-6X. And I do shoot off a front rest and rear bag on the bench with the 24X and will also with this one.

NOBODY can hold Rock Solid Steady, and a scope just magnafies the wobble, even off a rest to some degree....the higher power you go the more wobble you see. I took it down to the bench and could see a Lady-Bug on the Traget Frame at 100 yds, spots and all...............
