I shoot the same gun except I use #5 1 7/8oz, the Mag shok worked better than the premiums and last year with premiums I bagge one, one shot 47 paces. Seems to pattern good and if you can afford it try the Hevi shot, I tried them to pattern but couldn't afford them for hunting last year(laid off at turkey season) but you'd be shocked at how much better they are. I could see taking a bird out to almost 60yds if neccesay with the Hevishot.But If you like the federal,I'd stick with them, I do
