well i took my marlin 336 out for the first time today i went to a rang that only went out to 20 yards its the only range close to me, and im not sure if it was because of me or my iron sights or the ammo that i was shooting ( monarch is the ammo) but it seemed to keep shooting to the right what do you guys think? i did hit bullseye a few time though, but im thinking i need a scope, im choosing between nikon prostaff 3-9x40 or the cabelas lever action 30/30 scope
