something went wrong

[spottedpony]

My guess is increase the charge to minimum listed and the problem will go away. There is a phenomonon that occurs sometimes, of high pressure due to reduced loads. Something to do with the powder charge position and ignition rate when the primer ignites. I'd have to dig through all my old loading manuals to get the exact wording and reasoning but suffice to say, its apparantlly a documented issue.

Wow, pics would help a lot.

This is like trying to land a martian rover by braille- WITHOUT the metric system.

Thats called detonation and its 100% not whats happening here. People have blamed all manner of mishaps on it.

I would like to make an interjection here--but I don't know what to say

some of the brass deformed when I waspriming it.

How or why?

And using your toes to operate the controls.

From what I have deciphered the problem sounds like a primer problem. They aren't seating. Possibilities include improper use of the priming tool, undersize primers or oversize pockets, a ridge from primer crimp.

Have you changed primer brands or types? Knowing the brand and style might help. Also a measurement of the diameter.

Is there a ridge in the primer pocket? You might not see it, but usually they can be felt with a dental pick. Place the tip of a small tool in the corner of a primer pocket and drag it out of the pocket.

Can I make a suggestion? If you have a camera take some pictures of the after effect of the "blown out" primers first and post them along with a short video of you priming a case. I think that will go along way for the guys to see what is happening to help you solve the problem. Good luck

I dunno, but it seems kinda contrary that the primer pockets are worn out when it takes so much force to seat the primers that the cases are being deformed. Nor can I understand how with a tool with the minimal amount of leverage as a Lee hand primer provides, could bend the rim so severely to make the case crooked without damaging the hand primer. Those Lee hand primer handles are notorious for breaking even when used properly.


There's gotta be more to this than worn primer pockets.........

Nor can I understand his "Once fired" LC brass not having a crimped primer, or his 300 Blackout "once fired" brass being LC.

A lot just doesn't add up for me, with that, I'm leaning towards a mistake at the bench in powder and powder selection.

I agree with post #34 I have been a handloader all my life from about 1946 and have never had any such experiences. Must be I had a good teacher and coach. I could not even venture a guess as to how many cases I have primed. If one is not given all the facts he can't give an opinion.

 

[gamestalker]

I'm doubtful that will ever know the whole story, as it seems.

Agreed, to many ______ and not a lot of effort to fill them in.

 

[adaptandovercome]

I would like to see pictures.

 

[floydster]

Threads like this are scary to say the least
I have been at the bench since 1956 and I just wonder what all goes on out there.

 

[vulcandeathbuny]

I will try to upload pics as soon as I can. I'm offshore for the next 8 weeks the wife keep sending pics of the wrong brass. I appreciate all the help. as for as blank I am trying to fill them in. I don't get to get online all the time at work. whatever error I made believe me I want to identify andensure it doesn't happen again.
