The Western Field model 30 pump action shotgun and the Stevens model 520 shotgun are one and the same firearm.Savage/Stevens made these for Montgomery Wards.The shotgun in question should show that it was chambered for the 12 gauge shotshell.The length of these shotgun shells were 2 3/4in. If your shotgun is not marked,I would have a gunsmith make a quick check of the chambering for you.This will only take a couple of minutes to do.
Depends on what size shot, what size shell, what gauge shotgun, how good of shot you are and what choke is being used.. Generally 0-35 yards maybe more maybe less depending on all the above
