I've killed a couple 250-270....I did miss up and shoot at one 2 years ago that was a lot farther than I thought and hit it, was around 400 yards facing me I clipped its shoulder aiming at his nose....won't do that again but he did live according to cam pics...my most impressive kills are coyotes, working on farmland gives me opportunities to fire off rounds and hope for the best n I've killed several over 250
