The firearms community is all to willing to sell full auto sears,switchblade kits ad nauseum with tongue in cheek disclaimers about checking local laws. Tracer and incendiary rounds are inferior to dedicated flares because the greater velocity makes for extremely short burntime. A dedicated flare is short enough as it is. Early chinese ammunition brought in with SKS rifles was all hard steel core. I was at the Ventura Police range when an unfortunate soul managed to ( unkowingly) A. purchase one of the full auto versions that were shipped and B. set a brush fire with the hard hitting rounds. His rig immediately went bye bye. I purchased a large quantity of .30-06 ball for a M1. The seller had tumbled tracer and indendiaries to remove the tell tale orange and red I.D. paint. Several of us promptly took the stuff to the fire department for disposal after nearly burning down the Ojai Calif. range <img src="images/graemlins/blush.gif" alt="" /> Shotgun rounds are legal because dedicated flare pistols share common guages. Just because some outfit wraps their logo in eagles and old english script ammendment doesn't make them your shootin buddy.
