Well, I picked up a 700P in 308 2 weeks ago, I mounted my old tasco Varmit scope on it, hoping it would work for a couple months till I could get a better scope. Well I went throught a box of shells trying to sight it in! It was shooting all over. So I thought it must of been my scope. So I went out and bought a Bushnell 3200 Tactical 5-15X40 Yesterday, mounted it up this morning and went to sight it in. Well I shot at the target at 50 Yards, it was shooting low, so I kept adjusting up. I got it so it shot 1" low at 50 yards. I moved to the 100 yard mark, shot at the target, and I am 4" low, so I try to bring it up 4" and I ran out of adjustment on the scope!! What the heck is going on here? I am using a weaver base, and burris rings, everything was tight. This is kinda pissing me off...:mad:


UPDATE!!

Well I took the scope off, the rings off, and pulled the base back off. It is a one piece base. I installed the front 2 screws in it, and there was a gap were the rear screws go, about .009" So I cut some shims and installed them under the rear of the base. I then took the front screws out, and installed the rear ones, there was no gap, so everthing lines up great. Installed the rings, and the scope, went and shot it last night and was able to get it to shoot 1" high at 100yrds. Thanks for all the help guys!

Are you using the Signiture Series rings with the inserts? If so, my guess is that you've installed them incorrectly.
 
Try putting a shim under the rear of your scope base ( make a shim out of a alum.pop can)This should give you more adjustment .Hope this helps.

ALL Remingtons (Lately anyway) require a shim under the rear scope base. What a pain in the ass!!

And stand a good chance of damaging the score.

Get the proper base with a 20MOA slope on it.

I second that. The 700 SPS V I just bought also needed to be shimmed. But now it shoots like a hot damn.

If your scope ring are too high, it can produce weird elevation setting at close range sice the angle create is more important. Your scope should almost touch the barrel. If this is not the case I suggest using the technique underneath to avoid wasting ammunition.

Try to boresight it at 25 meters on a cross that is 3/4in thick draw on a piece of paper. Calculate with a caliper the height between your center of bore and middle of your scope using a caliper. Then mark that difference on that piece of paper. It should look like this :

I
I
I
I
+ this is where you should align your reticle
I
------------ You must align your bore with this cross
I
I

Make sure you are on a steady rest.

This technique will ensure that the scope and bore are parrallel and will ensure a hit at a 100 meters. That should be your baseline zero. Then you adjust your elevation setting for other ranges if required from this reference.

Hope this help

Make sure you have the right bases. Put a steel straight across the bare action - any gaps? rear lower then the front?

Odds are there is a mismatch between the action and the bases. The back of the action is low thus you are aiming low.

Solution is simply to level the bases by shimming the rear (getting a different rear base).

You don't want them to be at different heights while being 'straight/level'. That will bend your scope big time. If you decide to shim the rear base, make sure that the bases are absolutely level with each other before mounting your rings.

This action might be a good candidate for the Burris rings with inserts. That way any misalignment in your bases in height or angle can be compensated through the inserts and not your scope tube.

Something that should get resolved before any damage to your scope occurs.

Hopefully, the base screw holes are out of alignment either.

I know that they are more money, but why don't you try a better base like the nightforce 20MOA once piece base. That's what I have on my guns and I have never had a problem. Sometimes spending the money is worth it in the end.
