[QUOTE="Bart B, post: 100676, member: 5302"] [ QUOTE ] Have you tested any with and without a one piece base bolted on? [/ QUOTE ] No, I've not done that. I've got Medesha 20 minute aluminum bases for post-'64 Win. 70 long actions but they are too thick at the front for my dial indicator to fit on when they're installed. Come to think of this, I could do it optically. Clamp two low power scopes with a ring just behind their objective lens bell then mount one at each end of the base facing each other. Look through the back one into the front one then adjust the reticule until they both align. Next, hang the weight on the receiver and look through the rear scope. As the receiver and base will bend, the rear scope will now be aimed higher relative to the front scope's reticule. Click the rear scope down in elevation until both reticules coincide and I'll know the angle the darned thing bent. Of course, one could do this without a one-piece base, too by using the existing holes atop the receiver ring and bridge. The based receiver would bend less; how much depends on how tight the base screws were torqued and what material the base was made of. Mine are aluminum. [/QUOTE]
