A quick check on brickseek.com shows the walmarts in Waukegan and Gurnee, IL to have the Federal Game Loads in stock. Those are 1oz of 6's, at 1165 fps. Price is $8.58 per box. Not the best load out there for phez, especially late-season, but better than nothing.
I've had the new Sweet 16 for 3 years now, and couldn't be happier. Be aware though that the factory chokes pattern much more open than they're marked.
I use Trulock aftermarket chokes in mine. The light mod, with 1 & 1/8 oz of 5's is pure poison on wild roosters.
