Canted Bases?

Re: Canted Bases For Scope
Not sure I understand the rear mount being higher than the front. How will this help in long range? It seems that this would use all your adjustment in the up direction and would leave you unable to raise the crosshairs in the proper direction for long range.
If someone would be so kind as to expain this!

If you point the front of a scope down you are going below a target so you have to lift the gun up some to get the cross hair back on target . This has given you extra elevation of the barrel without moving the scopes elevation turret .
So now you have all the normal elevation adjustment that the scope has available at a longer range .
However it may make sighting at 100 impossible or difficult as it is not good to have the cross hair adjusted all the way up to get the POI down to 100 .
Similar deal at long range . So the compromise is a tapered rail that allows the scope to Zero at a much longer range and keep the cross hair more centred in the scope body and lens system .
