Primer reliability

[FLT]

I had a bad primer in a hand load this morning, A Remington 7 1/2 small rifle primer failed to ignite, it was hit hard enough and just for good measure I cocked the rifle and tried it again. Any way it got me to thinking, and I believe that is the first bad primer I’ve had in a hand load. I suppose I could have had one and not remember it as I’ve loaded for half a century. But I truly believe that this is the first one I’ve had . What I’m asking is are you guys getting that same level of reliability. What’s been your personal experience? I’m not interested in internet folk lore, personal experience only . Please and thank you for any input.

I haven't been shooting or reloading as long as some people on here, but I have had more Factory-ammo duds than my own handloads.

Most of the "dud" primers I've had in handloads I don't count as duds, because they happened while shooting double action with my .357, that revolver probably needs a new hammerspring. I've since switched from CCI to federal (which are softer) for my revolver loads and have had no issues.

I think I have had one dud .30-06 I loaded for my Garand, which I believe was a CCI standard large rifle primer.

I have been handloading since 1965,in that time frame i can only remember having maybe 3 at the most.I contribute that to mishandeling the storage of the un used primers.Not placeing them in waterproof container in high humidity areas.

My experience with misfires is that they are overwhelmingly due to firearms malfunctions except in cases of really old and/or poorly stored ammo. I don't recall ever having a misfire that I knew for certain was due to a bad bad primer of recent origin.

If it doesn't fire after hitting it with the firing pin twice, I would assume the primer is empty. I would then pull down the load and inspect the primer. It would not surprise me that a few in a 100,000 end getting processed. I have had similar issues with 22lr, where it just didn't seem the case ever got the priming compound put in it correctly.

I shoot more than average, so unsurprisingly I have experienced more true duds than most. I will say the nearly universal culprit in semi-auto failures is not seating the primer deep enough. It will take a decent dent and not go off, and I’m not sure why (I have a theory, but that’s all).

As far as true duds, I average maybe one or so a year. Hardly ever. Primers are one of the most reliable things I know of.
