My experience with Vortex is limited to a single Viper on a 22-250 but I would go with whatever reticle you prefer for your hunting. Let your son improve the rifle how he prefers when you give it up. I have a Zeiss Z600 reticle on my 300 Wby and while I like its function out to 600 yards it isn't better than knowing the trajectory and lots of practice. If you can't hit the target with a Plax it is way past 500 yards with that rifle.
Good advice, I'll let him decide, if and when, the time comes. Thanks.
