You are looking at the wrong rings on the Burris site. Burris doesn't make 1" low signature zee rings. It only makes mediums. You are correct about the extra lows which they apparently don't make any more. I have lows on my rifle.
You're also making an egg-shaped hole when you lap them. Only one portion of the ring will still be 1 inch in diameter - the rest will be larger. Lap a little too far and...
Sorry about the low size - you are correct.
I have used the dovetail/windage style of bases (i.e. Leupold style) with medium size Burris Signature rings on a few rifles, and they're right down to the barrel. On every rifle I own with Weaver-style bases and rings, the base always seems to be taller and I have to use a "shorter" ring to compensate. So, a low ring in your case may be needed to match your bases, but a medium ring with the Leupold style of base would work as well. Make sense?
I've got a 3-9x40 with Weaver style bases and the Signature Zee rings on my Vanguard, and it's nice and low against the barrel, FYI. You might want to try them as it's probably a better option than shimming and lapping in the long run. I also prefer my scopes as low as possible so I can understand what you're after. You can always put a -10 insert in the rear ring and a -20 in the front, lowering the whole thing a bit but also giving you incline.
