Re: Mount alignment?

Here is what I've started doing with scope setups that are somewhat limiting.
I turn the scope elivation nob down to 1/2 of a turn from bottom.Then put a one piece base on and the scope. Then I boresight through the bore and see where the x hairs are. I then shim the back of the base between the screws so that the xhairs line up with target.
Then the base is bedded tightened down so it stays put..
With the 20MOA base on the last 7mag the front actually had to be shimmed up a little to get the x hairs on target. With the IOR 6-24 set @ 18x that gives me 50 MOA of up in the scope and another 20 in the x hairs.

Re: Mount alignment?

Usually use whats laying around, cut peices of popcan or different sizes of welding wire. I actually prefer wire as it lets you get bedding under the mount easier.If the wire is a little too big it can be flatened a little with a hammer. 3/32 wire has worked well but 1/16th, .045, .035,.030 or .024 will work for lesser amounts.
I'm sure a set of feeler guages would be easier if available and they sell shims just for this kind of thing.

Re: Mount alignment?

I put the shim between the base and the action.Shimming the back of a one piece base gives you more elivation adjustment , shimming the front gives you less.
Once I have it figured out how much is needed the action and screws get a little relese agent and the base is JB welded to the action with the shims in place. The screws are tightened only so contact is made and let harden. After the bedding material has hard the screws are touqued down and exess is trimmed off.
If you look between action and the base you can see the bedding.
