I was in the Frederick Walmart tonight and swung by the sporting goods section to see what ammo they had in stock and the shelves were completely bare. I asked the guy behind the counter where all the ammo went and he said Walmart corporate directed all guns and ammo be pulled from the shelves.

I recently completed the MD W&C course with RS and his team and was very pleased with the instructors and content. Getting some time on their simulator was a nice plus too.
If making the drive to Joel Etchen, be sure to stop by Cove Creek Outfitters in Bedford, PA. They have a nice in-stock selection of Beretta, Blaser and Browning shotguns.
