Walmart in Round Rock (79 @ Red Bud) has turkey ammo on sale. Rem Nitro Turkey was marked @ $3.00 per box of 10 (12ga 3.5" 2oz #4).
Not sure how if it's good ammo as I haven't used in the past but seemed a good deal. The sales guy said Walmart is dropping turkey ammo from their inventory in the area. This was yesterday 8/8.
