after watching that deadlyist(?) warrior show the other night i began to wonder...not think....wonder. as not to claim i know stuff about this ammo, please be forgiving. has this been around for very long? is there a concensus that it will stay around and grow in popularity? i try to stay simple with the different types of ammo(mags,parts etc..) to stock up or keep on hand. it would kinda suck to get into that caliber if it is real expensive or not here to stay.
