[QUOTE="topgun736, post: 499773, member: 25910"] Lets talk about cold hard facts.There are no perfectly straight barrels and yes the factory drilled holes in the receiver may not be in line with the bore axis,that is why if we all buy the same rifle,rings,mount, and scope, chances are that the windage and elevation will be different on all of them when they are sighted in at the same range. Windage adjustable bases are an exellent idea,they are still being produced by several manufacturers and were designed to overcome these problems.Also purchase a bore sight collimator not for zeroing but to check your scopes performance. and to find the center of the scopes windage and elevation travel.Once you have done this move the base screws to zero the the rifle as you are sighting in off the bench. then do your fine tune with the windage knob. Yes I'm probbably given myself away here which is ok. I have built and serviced thousands of scopes in my shop for over twenty years, and we continually have scopes come into the shop with the windage knob turned all the way to the right or the left where the gunner behind the gun has turned that knob untill it stopped and then turned it even more untill they popped off the turret or pinned the iverter tube to the inside of the main tube wall.in some cases they have broken the inverter spring. the original Denver Redfields have the least travel in the varriable modles. The original Elpasso Weavers have alot more travel,but the one I have checked that has the most in a present day scope off the shelf is a Leatherwood Hi-Lux. [/QUOTE]
