I shot it right behind the shoulder standing broadside. I did discover that if I shoot less than 80gr or more than 100gr the accuracy of those bullets suck. I zero at 75 yds and shooting 110grs of powder makes the group go from around a inch to almost 3. I quit with 120grs just because I barely could keep them on a pie plate.
