Crushed and flipped primer handling?

If the primer isn't properly sealing the pocket I wouldn't shoot it.

You *could* set off a primer using a bullet puller on such a round, but I haven't yet with similar. The only time I've had a Winchester primer fire in a press was when I had crushed the heck out of it, on-axis. It takes a lot of mechanical abuse to set a primer off.

You get that kind of appearance with a primer that didn't start into the pocket "square" and even...

Disassemble both cartridges. Deprime just like you would when you resized them. Wear hearing protection and safety glasses. In over 20 years I have deprimed many upside down primers and none went off. Just move the ram slowly until the inverted primer is out. If there is no damage to the other case with the disfigured primer use it again. To set a primer off you really have to wack them hard and fast...I have never set a primer off using my error eraser (inertia hammer) either. That's what the inertia hammer (error eraser) is for in the first place. To disassemble loaded mistakes. Again...Safety glasses and hearing protection just in case...

I have had two backwards primers go off when I deprimed the case. I was prepared, and no harm was done other than the anvil got to the spent primer catcher in record time and it startled the dog.

Amazing...Hammer and a punch? Not to say it isn't impossible, but...

That IS why you should be wearing safety glasses and hearing protection...

Deprime it, and if you go slowly and carefully, you can even re-use the upside down primer. I do, for practice ammo.

Flipped primers on a Load Master

> Any hints on why this happens?

It happens because the weight of a full tray of large primers is enough to cause the priming system on the LoadMaster to move 'off axis' from the centerline of the brass being primed. Some primers will catch on the shellplate and flip right over as the priming ram moves up. Some will flip onto their edge and get crushed, others will insert into the primer pocket, but won't be aligned with the center of the ram. That's what makes the 'crescent' shaped indentation. The ram is off center and tilted on it's axis. The 'bubble of solder' is the lip of the primer that caught on the edge of the primer pocket as it was being inserted off axis.

The priming system of all progressive presses is fragile but the LoadMaster more so, because of the way the entire priming system isn't mechanically locked into alignment with the centerline of the brass as rotated by the shellplate. Sometimes the only thing keeping the priming system in place is the bottom edge of the shellplate stopping it all tipping up.

I made a bracket out of aluminum 'L' stock that runs underneath the primer trough and supports the weight. The bracket is supported by two screws that thread into the underneath of the threaded lugs for the 'arms' that hold the rounds in place as the shellplate rotates. No primer problems since I did that.

If you are interested enough, I could post some pics.
Should you have to do this for a new purchase in 2008 ? Absolutely not.

Here you go.

As you can see, the bracket is supported by the screws between the priming and powder station. Spacers set the amount of support and 'waggle' for the primer trough. Bracket is shaped so it dosn't interfere with press operation. Sorry 'bout the focus on the camera.

I had a primer similar to the one in the picture above. Today I decided to try and remove it using the de-priming die. It went without a hitch or boom.
