Ammunition Failure Mystery

I have not been able to reproduce the problem. After trying to reproduce the problem with critical duty ammo and my three hammer fired Ruger security nine compact pro pistols, I cleaned each one, loaded them with new critical duty ammo, and place them back in their staging areas. I’m now leaning toward Covid as the cause. image.jpg

Well this has me curious about the two mags in my trunk loaded with HSTs for probably six months. They’re kept in an waterproof ammo box along with a spare box or two of everything I shoot for when I’m at the range and having more fun than I expected when I leave the house.

One thought I had about the OP’s problem, perhaps the firing pin or striker channel was somehow gummed up from being in the trunk. Most oils tend to evaporate over time and turn into goo or shellac. Doesn’t explain why the rounds from the house fired when the trunk stash didn’t unless firing somehow loosened up a sticky firing pin or striker.

Striker fired guns, by the way, should always be dry after cleaning, not oiled.

Have you tried re-shooting the same ammo? Maybe you already said you did but I’m too lazy to go back through it at the moment.

Yes. Critical duty.

It seems odd that all the rounds you originally tried shooting went click instead of bang. If it was ammo related at least a few should have gone bang, that’s what makes me think it was probably gun related.

What I meant was, did you try re-shooting the same rounds, not just the same brand/lot number? My guess is you had a sticking firing pin or striker.

Some CLPs get real sticky when they’ve sat for a long time. Just a thought.

The one thing I didn’t consider was that the gun was very cold when I attempted the first rounds as loaded. I suppose it warmed up quite a bit after I successfully fired a few rounds. Maybe it was oil that waxed up who knows, maybe some spilled soda or something got into the hammer / slide. I just find it hard to believe all ten rounds had the same light strike mark without one detonation
