I have several sealed bags of this stuff. It is packed in 50 rd boxes, 5 boxes to the sealed clear bag. FFV produced, brass cased, mfg in 1987 or later. This was originally for the AT-4 anti-tank wpn sub-cal practice trainer. Tracer will burn red for at least 5-600 yds, easily out to 400 or so. It is designed for a single shot type trainer, therefore, it lacks the energy to cycle a bolt or slide of a weapon. This stuff is great...I pulled the bullets and re-charged with regular powder with no problems. Bullet wt is around 85 grains or so. I will not ship or sell to fire-prone areas of the country, so if you live in a banned state, I'm sorry. Prefer payment of USPS money order or bank check/money order. IM's accepted on the site, email will get the quickest reply. Price for a 250 rd bag is $185.00. Thanks for looking.
