Wether shooting bolt action, single shot or .223/5.56 chambered carbines this ammo really performs well! Decent priced brass cased non corrosive ammo, also reload able. I'll pay the extra few bucks to keep my firearms cleaner and precision accuracy from not using or shooting steel cased berdan primed bulk surplus ammo. I've shoot hundred's of federals 55grain fmj .223s and not a single FTF or jamming so far so Good. The only thing I did notice was one day when shooting my savage bolt action with a 1/9 twist I had a few flyers but it seemed to be from just that one box of 20rounds I was plinking out of. Otherwise Great affordable ammo that always goes bang! I always keep a few hundreds rounds stocked for the range and for here and there varmint shots. Thanks Impact Guns you guy's rock!
