FS/FT 10ga. Federal Black Cloud 3-1/2" 2 shot

[Mdclinks]

I am looking to sell or trade 10 boxes (250 rounds) of 10ga. Federal Black Cloud 3-1/2" 2 shot. Unfortunately my father purchased 10ga rather than 12ga before the waterfowl opener. Would sell for $25 per box or trade for 12ga. Federal Black Cloud 3-1/2" 2 shot, 9mm, or 45 auto. May also we willing to entertain offers on firearms (most likely plus cash on my end).
Thanks
Michael
