Is a scope an option? I have the same gun and have used it Ohio for many years. I use a 1x3 power and leave it on the lowest setting. Winshester BRI 3' sabotts work the best. (I tried them all). Get it on paper at 25yrds. A little high is okay. Then 50 then 100yrds. Leave it dead on at 100yrds and you'll be deadly anywhere from 50 yrds to 100yrds. You'll shoot over them at 25 yrds.
