will lower rings give me more elevation adjustment up?

That makes no sense! Raising the rear will lessen your vertical up range.

Move the rear sight (or rear of scope) the direction you wish to move the POI. Rear sight up moves POI up. Rear sight right, POI moves right.

I think of it this way. If the gun were in a vise and I fired it. Then i shim the rear sight up without ever taking the gun out of the vise the cross hairs would be shifted below the shot inpact. I would then have to brong windage down to get to zero.
 
Also I tried just installing only the front two screws of the base and and leaving the rear with out a screw.there is a noticable gap on the rear...

There is nothing wrong with your scope, and changing rings will do nothing.

The receiver of a rifle is course polished, and then fine polished to remove the tool marks - it is done on belt sander or automatic machines.

There is a specified dimension for the ring and bridge heights. For every 0.001" difference in height from the print dimension, there is a 1" change at 100 yds.

With the scope, there are ~40 moa of adjustment from the top to the bottom of the elevation turret.

So, in a perfect world, you put your scope on the action and it lines up perfectly... and you loose 20 moa of your elevation before you have ever fired a shot - most guys rifles cannot shoot past 600 to 700 yards, because there is ot enough elevation. Now, add some variables to the soup, like the front ring is a few thou over, and the rear bridge is a bit low, and. BINGO, you are out of elevation, before you start.

The solution is NOT to bed your mount, that just adds more unpredictable garbage to the soup.

The solution is to get a pair of Burris Signature rings, and then you can add what elevation you need to the rings, plus you get the added protection of never marking up the scope tube with "ring marks".

I use these rings, and set them up so my 100 yard zero is at the very bottom of the elevation adjustments, so I get full 40 moa of "up" (which is what I paid for!!)

Thats your problem you need to bed the scope base and you will be good to go. This is a VERY comon problem with 1 peice mounts.

here is a link

Link is for a rem 700 BUT WORKS ON ALL RIFLES just follow the video!

I purached a set of signature rings. So off to the laboratory later today so I can mount em. I hope the plastic ring inserts hold zero year in year out.....

They do not change...

I'm not a fan of Burris rings, or any rings that use an insert, for that matter. Your base my be mis-made or out of spec. You can try another base or it can easily be machined to custom fit your rifle. Then use the lowest Leupold rings that will allow your scope to clear everything. The next step is to ream or lap your rings to true them up for any out of round or tilt/alignment problems. Mount your scope and use a torque wrench to evenly torque ALL base and ring screws. If you think you might be getting in over your head, PM me and I'll help you out.
 



Use Auto spark plug feeler gauge stock. It is hard but you can drill it. I use a cut off wheel on a dremal tool to cut it. Just find one that fits.
 
Just use some JB Weld instead of a shim. I put some wax on the receiver, the screws and screw holes and then placed a dab of JB on the mount. I then tightened only the front screws and let the JB start to set up. Trimmed off the excess and removed the mount to make sure it wasn't glued to the receiver.
