I have a case of 300 Hornady 50 caliber (.510) 750 grain A Max Bullets. $1.60 each. These are not in individual boxes but I can count out whatever quantity and bag them up, bubble wrap them and ship in a USPS flat rate box for $6.
For example - $32 for 20 bullets, these go for about $48 per 20 on most websites.
I can Email a pic if needed.
ETA 100 sold - 200 available.
BTW these are bullets and NOT loaded ammo.
