Since shootin one with the bow means everythin has to be perfect.I'd use the gun first.You may have a few birds come in that won't give ya a bow shot but could be taken with a gun.Get the gun one first and that gives ya more time to get one with the bow.As for callin it's alot easier with a bow if someone else is callin.It diverts the birds attention from you and gives ya a better chance to draw the bow without gettin busted.
