Can't get enough elevation out of my scope....

I can't swap the bases, but shimming up the front base makes sense. The scope is new.

If it shoots low you want to shim up the REAR base;) not the front. I usually use plastic shim stock, I bought a book of different thicknesses from Aclands for about $10 years ago and still have tons left.

300yds with a 30-30, if I could ,i wouldn't. In placing a shim, I would just place it under the scope? To put it under the base would be hard be pretty hard on a Win 94 AE

I read some where either CGN or a gunsmith book,
that it said to use pop can alluminium . Make a shim and install
it in the ring sadle where the scope sits in.
Experiment with single or double piece untill you get where you want.

I wanted to post that for giggles.

If i was a fan of "see throughs",
the only gun i think i would put it on would be a lever 30-30,
because of the up close shots in thick brush possability's.
I use a receiver site. Something about an old style gun
that doesnt look right with modern glass optics on it.
I supose if your eye's are not as good as they used to be,
you might have to consider it.

I don't think it should go in the ring saddle as that would mark the scope in that spot for sure when the top saddle was tightened down plus I don't think the scope would seat in the bottom saddle properly. Under the base is best IMHO. Using pop can material as shims is a great idea though.

Ring saddle seams like bad idea - reducing the circumference and roundness of the ring, scope tube may not like that.

Underneath the rear base better idea or depending on how ring mounts to base, it may fit between base and ring too (thinking of the angled clamp type rings - would just mate to the ring lower down on the angled part).

Pop can walls are about .005" I believe so may need more than one layer.
 
Why the hell see through mounts?

You must have to shoot that thing off your nipple to get a sight picture. :D

For the love of everything unholy please Install shorter mounts. :)
 
I'd start with .007 but it really is trial and error... :)

I messed up on my earlier post it was the rear base I put the shim under I edited my post already.
 
after reading more post's, yeh in the sadle wouldn't work too well,
but would in base's that where screwed down to reciever.
Groved rimfire recievers would be another story.
 
looks so cool :rockOn:

my experiance with these see through mounts is that they are awful flimsy.
before u shimm, take the scope off and use a straight edge in the bottom
on the ring saddles. this will tellu if one is squished and maybe swap
ring positions. i have used a piece on 1 inch shaft and a deadblow
hammer and squished these seethrough mounts to line them up. i don't
recomend this.

so, How much would i have to shim, i have all kinds of shim stock at work .005, .007,
.010 of brass shim stock

totally dependent on the length in between the bases, and now, it also totally depends on what kind of movement you can have in your scope!

do you know how many clicks it is back for the scope to be centered vertically?

measure front of the front ring to the front of the back ring. That will give you a rough ctc measurement. If you are 4 inches low at 25, and almost a foot at 100, then you need somewhere between almost 12 and 16 MOA to zero. You gotta add to that how much you've already adjusted out of your scope.

According to bushnells website, that scope has 120 MOA adjustment. That would be 60MOA up and 60MOA down. Lets figure this is a perfect world, and just go right in the middle, that you need 60 + 14 (right inbetween 12 and 16) MOA. 74 MOA adjustment required.

Lets say CTC bases are 5.1 inches apart as per bushnells website.

5.1 = diameter of imaginary circle.

5.1 * 3.14159 = 16.022109

16.022109 = circumference of our imaginary circle

16.022109 / 3600 = .00445

.00445 of shim would equal 1 MOA.

you need 74 MOA, 74 * .00445 = .329"



Now, all the ifs for the prior info: If you are currently out 14 MOA, and your scope is 60 MOA from center.
If your bases are 5.1 inches apart CTC.

Let me know if you need another calculation done :)

Good luck!

ps. .329 is a hell of a lot to shim. Will be bad for the scope unless you have a 1 piece base, or burris zee rings.
