ive got a nova also id pick up a hs strut choke. they have one for lead and one for hevi shot. and run around 20bucks
if you choose the lead id try win. hv 31/2 #5or 6 to lessen the amount of shots i would start at 30 yds and then 40 and 50
im 16 and weigh about 140 wet but when im shooting at a live bird you dont feel it at all and i HAD to take a 60 yd shot last season and came out succesful
