I'm planning on trying out the FPB's soon. I've been having trouble finding them in the Albuquerque area. Walmart finally got some in but at almost $19 I'm having a hard time getting myself to pick up any from there. I did find a shop in, of all places, Mass. that is picking some up for me this week from his supplier for $14.10 per pack, I ordered 2 packs and he said he would get an extra 2 packs just in case. I will be back up there this weekend and will pick them up on Monday. I won't be able to try them out until the following week when I get back home. I am hopping to go to the range the end of this week and wish I had some to try so I may choke down the price and get some at Walmart. I've checked with Sportsmans Warehouse and they didn't even know what I was talking about when I asked about them.
