I usually ight mine in 2in high at 50 yards and im good out at 100 yards. But i shoto a 12 gauge. I get on paper with cheaper slugs and fine tune with the slug i plan on shooting. I get on paper with Brenneke KO slugs and they shoot 2in high and 3in right compared to the Federal Barnes Expander slugs i hunt with. Your gun will be different but you can try it.
