Issues with White River Energetics Large Rifle Magnum Primers

[Mark37082]

If the firing pin is using energy to push the primer deeper into the case, or its using energy to push the case forward there will be a dent just like what you are seeing, but no (BANG)

They must be some tough or short primers. I can only recall one failure to ignite primer in 40+ years of shooting. It was factory ammo. So I am not really qualified to opine. I've always treated primers with care. The picture provided looks like it is more than just a dent to me.

Hey mackgee & gang, my bad!
I thought he was fire forming his cases.
Disregard my prior post.

Many years ago when loading some 38 special wad cutter target loads I ran out of my usual, at that time Winchester small pistol primers. There were no Winchesters available at my local gun shop so I bought a few sleeves of CCI small pistol primers. It's a good thing that these rounds were being loaded for personal use since 41 of the 200 rounds loaded failed to fire, even on the second attempt. During practice this was an inconvenience, during competition it caused my disqualification from the match. I avoided CCI primers for many years because of this. These days I don't purposely avoid CCI's but usually prefer both Winchester and Federal depending upon the application.

I was lucky, during the period when loading components were not available due to COVID. I had enough primers, powders and bullets to allow me to continue to shoot, albeit at a lesser level than I liked, but could still shoot. The one thing that I regret is not resupplying my stock of IMR 4320 before Hodgdon quit making it. My highly accurate 308 and 30-06 match ammo was based on IMR 4320. Still looking for a powder with similar performance and yet to find any. Do any of you have any recommendations?

540 is close to 4320. I got lucky and picked up a keg of 4320 for my 375 before it went away. There are so many stick powders in that burn rate range but many of them like 4895 and rl15 have gotten really spendy or are hard to get lately.

It seems RL-15 is going bye-bye along with ALL Alliant powders!

Do you want some cheaper bullets to use for fire forming? man I bet those burgers are $$

To my eye…the fired vs. mis-fired case looks identical in terms of primer strike.

To me, this is showing the case head was not against the bolt face during firing.
FTF on left probably pushed forward during firing pin strike, causing what appears to be a light primer strike and deforming the primer cup.
Fired brass on right slammed back into bolt face causing flattening of primer. I highly doubt that is actual overpressure causing the flattening of the primer with fire forming loads. Fire forming soaks up a lot of pressure to reform cases. I have thousands of fire forming rounds under my belt for wildcats and other improved cases.

Hey guys - anyone wanting FREE Hazmat with purchase of $99 of powder/primer and they have some LRP in stock check out Midsouth. I just picked up another 1k of White River LRP and a few lbs. of powder just for fun.

Really? I use R17 in my 6.5 CM. What is happening to the powder market?

Yup hate to say but yes. Alliant has stopped producing commercial powders for reloaders. They have too many orders from the military and are producing powders for them currently.
