The PD I retired from had problems with lacquer building up in the chambers and causing malfunctions. The steel cased ammo was purchased by Troopers and shot in dept. AR's. After the problems arose the Dept. Policy forbade steel cased ammo in Dept. AR's. My PD used Bushmasters, Armalites and Colt M-16 A-1 military surplus rifles. Range officers didn't think it was worth the risk of using steel cased ammo in a gun you might stake your life on. I've always felt brass was the best and have never fired any steel cased ammo in my AR's.
