Possible Squib?

Hello, all.

Last Friday, a couple of friends and I were at the local range. One of my friends, Jim, was firing his "military unissued" Yugo SKS for the first time, using Wolf ammunition.

As we were stationed at separate benches firing our own rifles, we were not monitoring each other. After the range session, Jim indicated that he had experienced a jam in which the bolt had partially stuck open while extracting a spent case. He also recalled that the recoil for that discharge was significantly less. Jim managed to clear that jam by forcefully pulling the bolt carrier back and ejecting the stuck case. He then proceeded to fire another couple of boxes of the Wolf ammunition with no problems.

Thinking about what happened, it appears rather likely that the jam was caused by a "squib" round, i.e., a cartridge with little or no powder. The lack of recoil also leads us to believe the projectile did not clear the barrel, and remained lodged therein.

If that is in fact what happened, I think we were lucky that the subsequent rounds discharged did not rupture the barrel.

The SKS was closely examined after this, Visually, there did not appear to be any damage to the barrel, and no change in resistance was noticed when running a bore brush through the barrel (that might have indicated a bulge).

What else can be done to ascertain if his SKS is still safe to shoot?

I have a feeling a squib would have been quite a bit more impressive than what you experienced.

If it was a squib, and the barrel is now clear, it's too late to worry.

If the barrel was to bulge or the gun blow up, it would have happened when the 'next' shot was fired.

If it still works, it's as good as it's going to be. By the way, there are lots of guns (of all sorts) out there with slightly bulged barrels. Typically the accuracy suffers to some degree. But they are safe to shoot. And if you checked it with the patch routine, it's fine.

Commence fire. Do be careful about low recoil rounds, by all means.

It sounds like the round had enough powder to get the bullet out the barrel, or else the next round would definitely (no "luck" about it) have bulged the barrel.

Good rule: Anytime a round does not sound right, or a semi-auto rifle does not function correctly, ALWAYS check the bore before firing another round.
