Has anyone ever had a primer go off when seating it?

No in 45 years of loading and never heard of it. But I'm always cautious, I have Lee press attachment, wear glasses and sit lower than the mouth of the brass.
 
Has anyone ever had a primer go off when seating it?

i had one go off on Sunday while installing some Federal LRP into some .243 Win brass.

Luckily it was pointed away from my face,gave my wife a scare though.

Hornady hand primer with the appropriate large rifle primer rod.

First time out of probably 5000 rounds loaded.
Never for me in 55 plus years . Lucky 🍀 probably.
Any how - any damage to anything or just - What 🤷🏼‍♂️ BANG and some smoke ? or ? RJ
 
I prime by hand and have never had a primer go off when priming. 30 years of handloading with Lee stuff.

I know an experienced reloader who had his new Dillon blow a whole tube of primers. After an underwear change he also installed the blast shield.

.
I prime using the Lever Primer System on the Lee Classic Turret but I don't use their Safety Prime Tool. I place them one by one from a primer tray and have also disabled the auto indexing. I have never set off a primer and can still make 100 rounds in 30 minutes which is good enough for me.
 
I don't even want to guess how many rounds I have loaded, it would be close enough to 300,000. I have personally never set off a primer however, I was teaching a friend how to reload and he set off two in one session with an rcbs hand primer. He would squeeze, let off and squeeze again. This put a primer partially into the pocket and allowed another one under it. No damage or chain reaction. The safety mechanisms to vent the gasses worked as intended.

Hey Jim,i bought some 300WSM cases from you a while back on GP.

Hope all is well.

I had the case pointed away from me when it went off but i caught the flame coming out of the case neck out of the corner of my eye.

Wife was watching Yellowstone and she may have peed herself a little.

:D
 
never had it happen to me, and I've set primers up side down and crushed a few sideways and done a lot of depriming brass / removing live primers to salvage some primers.
Same here just lucky I guess, but it still may happen , I’m not done reloading yet , but I seem to be more careful the older I get , been reloading since the early 80’s

This could be used as a classic example of why not to "re-seat" high primers in a charged cartridge...you are messing with a "small live hand grenade" to do so.
