again not an expert on vortex OR moa for that matter but what it will boil down to is what ammo you are shooting and its MV. that will play into the dope being spit out by your ballistic calculator. if you are concerned, just take the mv listed on the box (which isn't perfect) and run it through your ballistic calculator. that will give you a ROUGH idea of how much moa you will need out past 200. then you can tweak from there
your zero is important but most guys who shoot rimfire prs style matches or shot out past 200 yards use a 50 yard zero. trust me with a 30 moa base you should be good to go. lots of good options for them out there
My concern is that with a 30 moa vase on a rifle with 32.5 moa of useable adjustments, 65 moa total adjustment, I won’t be able to get a 50 yard zero. Is this a valid concern?
