I have a 6 X 24 Bausch & Lomb on a .223 varmint rifle and it’s just fine at high power off of sandbags. Of course you need to crank it down if you’re using it off hand or from a bipod.
But off of bags you can shoot egg sized targets with it at 200 yards and decide what part of the egg you’d like to hit...
i don’t usually use bags. but i figure if i can hit golfballs from 200yards off a bipod, i’m doing pretty good.
