im more of a thousand yard guy myself, but hey, to each there own.....In the famous words of @Pete Correale,
“Sheeeee’ll eat!”
503 yd kill which is starting to stretch it at 10x on the Mark 5. Ran the data on it and you’ll still have 1000ftlbs of energy out to about 695yds with the Berger 168 load from Federal, but that’s definitely pushing this optic too far.
