Based on several other recent threads I decided to go test some of my 800rd+ stock of HPs in my Bulgie and rebarreled [9x18] IJ-70. First I tried some of the older GA Arms HPs, fired a full 8rd mag, followed by a 5rd mag, using each Mak. One round would not chamber but upon dropping the mag and reloading the round in the mag and feeding it, it worked. No big issues here except I was all over, under, and who knows where some of them rounds went. Haven't fired my Maks in 4 months or so, so maybe a good part of that was me, and it showed.
So, nothing interesting yet.
Next, I fired some older Hornady HP rounds. I got these from George Fisher about 3 years ago, so no idea of age. I had one round that was a little weak causing me to stop firing, drop mag, and check stuff out.
So, nothing interesting yet (wait for it, its coming)!!!
I think I had 23 rounds of this stuff to use up and round 21 just didn't sound/feel right and also I immediately noticed a LARGE amount of powder smoke pouring from around the slide and chamber. Not your normal post shot smoke residue, more like 8 times the normal amount.
I immediately yelled "Cease Fire" (other shooters where on the range), and dropped the mag, and locked the slide back. I cycled a round out doing this and noticed that the cycled round projectile was noticably depressed into the case. Next the RSO and I noticed a squib round so close to the chamber that when the slide cycled the next round and forced it into the chamber, the end of the round hit the squid round, causing the projectile depression [shown below]. Also, the unburnted powder seemed to be wet from the remains of the squib round. The temp was about 30 degrees or so. I had no issues with any other ammo all day, just these rounds. I also noticed that these rounds seemed to leave lots of residue like unburnted powder. Noticed it when changing mags.
Here are some photos:
My first squib round. Guys, be careful out there!!!
