I've had problems with their .223 also. FTE on third round of mag. I was firing single shots then fiddling with red dot in between, on my Benelli MR-1. Casing stuck in chamber so tight I had someone at range try to help get it out. A rod down the barrel wouldn't budge it. I was told the lacquer on steel casing essentially "super-glued" itself when heat from barrel warmed it up. Broke it down at home and used a steel rod and a dozen bad intention hammer swings to break it loose. Never had a similar problem with their steel pistol ammo, but might just be the Benelli which get REAL hot or possibly Russian "quality Control"
