I took my new Lancaster AKM to the range today for the first time. This is also my first AK of any kind, so I'm not too familiar with the operation. I had about 10 mags loaded with 5-10 rounds of Wolf FMJ and JHP. The first 30 or 40 rounds were fine, then I started to have problems. It didn't seem to differ when switching between JHP and FMJ. I chambered a round, fired and then CLICK. Cycled out the round and chambered a second and fired. This occurred several times before I noticed 2 things. One.....the rounds I cycled out by hand had primer strikes.....and 2..... I began observing the bolt carrier getting hung up about 1/2 inch from full battery. I can't determine what is causing the problem. I believe the bolt itself is catching as it approaches the chamber and attempts to rotate. I took it home and cleaned/lubed the rifle and it seems to working a little better cycling by hand, but I'd like to know everyones thoughts. I can also get the bolt carrier to hang up if I slowly pull the bolt to the rear all the way. Is this normal? I also found that I can "set up" the problem with an empty mag and chamber. I can manually ride the bolt forward until it catches about 1/2 inch from full battery. Then when I pull the trigger, the hammer drives the bolt forward into battery. Am I in danger of having a kaboom?.......or is it impossible for an AKM to fire out of battery? Thanks in advance for any advice.
