Took mine out today and shot the non corrosive norinco ammo I bought from canam and some surplus I bought from a cgn member. Both fired flawlessly, I shot 30 Norc and 100 surplus. The Norc primers are a lot softer then the surplus ammo big difference in the primer strikes, but like I said I had no issues. Impressed with the gun and even happier that it shoots cheap ammo
