I said this ammo was better than using your fist or throwing rocks at an enemy....but funny you should mention the lacquer problem...never thought of that...we shoot full auto and of course we "gum up" our guns...but we have break free and boiling water handy on those big mg shoots for corrosive and "crap" ammo.
bragger!
P.S. If you reload, Bushmaster has PMC 223 brass for about $25 delivered per 1,000. Using Benchmark powder (outstanding temperature stability and consistant velocity), and a variety of bullets (55gr Noslers Ballistic tips my favorite, cost more though) I reload for about $120-$140 per 1,000, and get near match grade ammo that I trust. I also seal the primers and crimp with a professionally result.
