Thanks
I just figured the farther forward the scope, for a given change in eye position the smaller angular displacement, and angular displacement from center of lense is the cause of the parallax.
guess on a 357 I shouldn't be shooting far enough to miss the target or game for this reason. Will have to experiment. BTW I got the one with the solar panel on top, so should not have to use up batteries except in very low light times.
thanks Don
