I've got a Leupold Vari XIII 3.5-10 tactical with the mil dot reticle but no parallax adjustment. Great scope. I only started shooting to 500 yds recently and would like to put this scope on my main gun, instead of my Leu Vari XIII 4.5-14 WITH a parallax adjustment dial. WIll this be ok, or should I use the 3.5-10 for my deer/yote excursions only. Thanks in advance.
