HA! Don't complain about Wolf...the supply of XM193 is real tight. First it was Q3131a, now it's this...even AE .223 is selling out in a lot of places. All that is available is the XM855PD, which is a 3rd tier reject load, and that is selling for premium price.
A lot, I mean a lot of AR-15 snobs are finally biting the bullet (haha) and buying up Wolf .223 like crazy. Before the .223 shortages, Wolf = pure garbage that would never be run through their rifles...
I'd say a number of factors are causing ammo to go up in price and for supply to dwindle. A major factor is uncertainty these days. More non-SHTF anticipators are now changing their thinking and are doing some shopping post-Katrina. When regular folks start hoarding SHTF ammo, we "extremists" are inconvenienced. Due to gas prices, UPS is jacking up their shipping price. Ammo is heavy. Then there are wars all over the place, all of which consume either AR or AK ammo....
