Thats crazy! $50 for 20 rounds,, quality steel(tail, body, beak.. boom... dead bird) at reasonable prices,, you cant beat fasteel. Get some 3.5" #2's at 1550 fps,,, they work really good, on anything within range!
Honestly though ive bought it a couple times,, too many other expenses in duck hunting to justify that much on ammunition,,, trust me,, you'll see... THE MOST ADDICTIVE TYPE OF HUNTING THERE IS!
