I don't know about this supplier. There prices look good for S&B although I am not sure whate the shipping charges and handling charges run. I will be interested in the responses.
I believe Natchez Shooting Supply has the 9mm ammo on sale for about $100/1000. However, I don't know hat shipping and handling charges compare.
As an aside, I have heard nothing but good about Ammoman and have been very pleased with the service I have received through them. His prices are higher but they include shipping so I don't know where you end up on an "out-the-door" comparision.
Play hard, shoot often, leave well worn guns!
