“Burnt” primers?

[New264gunner]

Good Evening,
Had a misfire at the range. Primer had a very adequate impression. Upon pulling the bullet, I noticed the powder was discolored. I looked in the spent primer catcher and noticed all the primers looked burnt.
Unfortunately I was unable to identify which primer had misfired.
Any information/advice is much appreciated.

Looks like another one to the right hand side as well

Just from appearances it appears it wasn't seated deep enough. Anvil riding high.

With the scant information you've given, it looks like some of the powder tried to burn but the fire went out. See the yellowish kernels?

Last time I had this, along with a couple of hang fires, I hadn't dried the cases fully after wet tumbling and there was still a drop or two of water that had accumulated on top of the primer before the powder went in. One of the hang fires was just over 5 sec, about the same time I usually recock the bolt for a second strike.

Water in the case will definitely ruin your day.
I prefer to set mine out in the summer sun when I can. If not that time of year, I put them it a 250° oven for an hour.
And I STILL let them sit for several days before reloading.

Why would it look burnt if the primer and powder didn't go off? Never had an anvil fall out of a fired primer. What do the new primers look like? Definitely some kind of powder contamination. I dry my tumbled cases in the kitchen oven at 190F. Higher temp discolors them. After about 1 hr. at temp, I turn the oven off leave them in the oven cooling down over night. I was shocked at how much water was still in cases after shaking them hard one at a time by hand. Did the anvils fall out because the primers were a long way from being seated at the bottom of the pocket. Detonation blew them forward?

Water in the case.

Keep your powder dry. The loudest noise on the battlefield is click.

If not Summertime and hot out, I will put the cases in an old food dehydrator for at least 6 hours. !2 hours if I plan on loading right away

OP said in anorher post.
"I have a pre ‘64 Win. M70, .264 WM Trying to preserve the barrel by working up more mild loads with flat base, lighter bullets, such as 100 gr. Sierra..."

When powder starts burning & stops, something is very wrong.
Needed-
1. Mag priner.
2. Faster burn rate powder.
3 Bullet base at neck soulder junction.
4. Good bullet hold. This increases start pressure.

Old discontued H450 BALL powder started burning in my 22-250, about 50 years ago. Was using a mag primer.
Pulled bullets showed part of the powder burnt, turned golden and clumped together.

If the OP would comment on the exact load / Rifle? May help?

Other wise, i can just guess.

Wow. When I wet tumbled, I dried for an hour because it was easier to set than anything less. I was running at 70 degrees C (which, according to Google is 158F.) I was, however, using a rack that held the cases mouth-down, so there weren't any standing puddles inside. Never had a moisture problem (I did have a wet dry tumbling media problem, but that's another story.)

water goes - UP - when it evaps
perhaps turn your cases over and let the standing puddles evap upward out of the case mouth taking the path of least resistance ?
trying to evap through the flashole is more difficult to go UPWARD through
even more difficult if the spent primer is still in there trapping a cloud of vapor
