I got an order on the way. They came "in stock" for another ONE day and are out of stock again, now. $84.99 for 1,000. I will test them after receiving them next week, and post results to my bang test, and ease of seating (compared to the S&B I am running out of (those have been reliable, seated well and no complaints).
Re: Midsouth, you need to check every morning and order promptly when they are available. They currently have about 90 powders in stock, so I grabbed a pound of BE-86. Midsouth's Hazmat is $20 now.
