They are extremely popular with USPSA/IDPA shooters, so they go fast. I've always had good luck calling them for availability. Usually it shows out of stock, but they've always had what I needed (180gr JHP's) when I called. They have the best prices on 180gr JHP's, and they're great bullets. Maybe look at Montana Gold, Precision Delta (no 10mm JHP's), or even Xtreme Plated HP's. The Xtremes have a thick plating, so they can be driven harder than other plated bullets.
