Thread: Running out of elevation adjustment - advice

I may be wrong, but I seem to remember that the Burris signature scopes have a sort of zero stop that wont let you get full elevation travel out of the scope without adjusting something within the turret. Ie it only lets you spin the turret one or two revolutions or whatever it is past your zero stop. I think.

So you'd go as high as you can. Then adjust whatever it is within the turret. Then you can go more up again after that. I think.

put a straight edge across your 2 scope bases and see if the front base is indeed higher.

Has 2 piece rem700 bases on it with some unknown rings and a Burris signature 5-25x50 scope, have tried sighting it in and am always running out of elevation up adjustment at about 50 yards. It's usually 6inches low before it can't be elevated anymore. I have turned the scope dials each way counting clicks etc to get back to the center, also tried another old scope and shimmed the back base with the same issue happening.

I might be missing something simple but does anyone have any ideas? I'm thinking it might need some different bases

Thanks in advance

Greeting again,
I had some Parker Hale bases for the M700 out in the shed so did some rough measurements. The rear base is around 2.5mm or so thicker than the front base. Your odd ball front base is thicker so a shim would have to be extra thick, 5mm or more, so it is not surprising it did not work out for you. As mentioned before just get the right base or better a rail base either 20 MoA or straight and the problem will disappear. Hopefully your scope is not damaged.
I had to fix exactly this problem for a friend some years back. He had decided to fit an old Pecar image moving scope to his rifle and the reticle wound up high in his scopes field of view. The problem was traced to a wog base. It always pays to look at the simple things first.

Thanks for the help everyone its much appreciated. bit of a rookie missing something so simple, still young and learning

I put a straight edge across the 2 mounts and sure enough the front mount is alot higher, so I'll grab the correct mount tomorrow and will give it a test run in the weekend

These scopes also have a zero stop so that may be causing you a problem if you haven't reset it from when you bought it.

Greetings,
I thought the word had gained a wider meaning of something out of place rather than the original acronym hence the use of lower case. Perhaps I erred.

Ditto

Changed the front mount, got a zero then shot this group at 300y. Luckily the scope wasnt bent. Thanks for the help everyone simple fix
