Having problems with my WASR 10/63. Gun is new- bought it as a plinker. Here is the story: Brought the gun home and cleaned it. Took it to the range and had 15 FTF out of 100 rounds. Was using Monarch 123Gr steel case from Academy. Frustrated about the 15 FTF so I stripped it down and recleaned with Break Free and CLP. Reassembled and took back to the range tonight. Tried different ammo. Winchester White Box- no problems with 20 rounds. Wolf 124gr HP 6 FTF out of 40 rounds. Monarch 6 FTF out of 60 rounds. I then put a few of the rounds back in that did not fire and they fired the second time around. Tried taking a pic of the primers but they are blurry. Does this sound like a Headspace problem? Firing pin? Or just normal for this cheap ammo the have so many FTF?
