Does the groove size make a difference in scope alignment or parallax, if I use 3/8 in.(10mm) rings in an 11mm dovetail groove? I just bought a CZ 512 with 11mm dovetail groove and I need to know before I buy the wrong rings. I mounted a scope i had on another .22 but those rings are for the 3/8 in. grooved receiver and don't want to waste ammo on siting in something that won't work but at one distance or that i have to shift to parallax correct for varying distances. Thanks RZ
