Anybody familiar with this stuff? Got a mailorder catalog today offering ammo from Dynamic Research Technologies. It's supposed to be the most deadly and accurate ammo available. The ad says it has a powder core as opposed to lead or solid copper. The powder is of course in motion as the round spins, giving it (so they say) incredible balance and accuracy. If it hits an organic target -- your garden-variety home invader -- the powder "instantly disperses, resulting in Instant Death." their caps, not mine. Average wounds are five inches deep and 5 inches wide; the bullet turns to dust. Hard to print a serial number on it, I'd guess. The ad only offered two calibers, 124gr 9mm and 79gr .223. Cost --wait for it -- $70 for 50 rounds of 9, $50 for 20 rounds of .223. Love to hear if anybody's used it or read about it ... I've seen nothing in the gun mags I read.
