Priming Kaboom — Primer Flash Sets Off Multiple Primers in Tray

primer flash explosion Hornady handheld primer tool kaboom

Here is an important safety reminder for readers who employ hand priming tools with trays of multiple primers. In this instance a primer detonated while being seating in a pistol cartridge case. This caused a “flash-over” which instantly ignited multiple other primers in the tray. That, in turn, caused a small explosion which broke the tray and Hornady Handheld Priming Tool. The user, a Forum member, posted this report this morning in our Shooters’ Forum.

I had a small scare the other day while reloading. My experience might be a helpful reminder to people to keep safe and follow proper procedures and not be sloppy.

A primer popped (went off) when being seated and (while hot) flashed over into the tray causing other primers in the tray to detonate. That, in turn, broke my Hornady Handheld Priming Tool and injured my hand.

Here is my loading area after the incident. Note the damage to the hand priming tool. I’m not not sure where the rest of the pieces are.

Injuries to User — Multiple Cuts on Hand and Forearm
This photo shows the resulting cuts to hand. Fortunately they seem superficial. Note — I was wearing latex gloves so my hand had some protection.

The blast also blew my glasses off my face and they landed about six feet away. Be careful folks and wear your eye protection! EDITOR: Guys — This is yet more compelling evidence why handloaders should always wear eye protection!

More Details — Primers Were Federal LP, Case Primer Pockets Had Been Checked
The forum member noted: “Just in case people are interested, I didn’t notice anything different from usual. Cases were Privi Partizan (PPU) factory brass on their fourth firing. The primers were Federal Large Pistol. The cases had been ultrasonic cleaned and the primer pockets checked prior to priming. I had primed around 50 cases during this session before the accident.”

Here is a close-up of “flashed” primers — note the empty but dented cups and triangular “anvils”:

This incident happened using a Hornady Handheld Priming Tool, as shown below.

Two other Forum members reported feeding issues with this particular handheld priming tool and one other member, Kiwi Greg, suffered a multi-primer detonation causing injury: “I had the same thing happen a few years ago now with the same Hornady hand primer with 50-75 [Federal 215M primers] in the tray. Made a bit of a mess of both my hands, blew primers and tray all around my large workshop. Scared the [heck] out of my employee who was near me at the time. Some stitches, bandages and it was all good, [but with] some wicked scars… I think a primer had turned side-on when being put into Bertram .408 CT brass which had nice tight pockets and required more force than usual. I use RCBS [priming tools] now with a flat bar that slides across to prevent sympathetic detonations. I hadn’t heard of it before, but found out it wasn’t that uncommon after it happened.”

Pistol Skills — How to Diagnose Handgun Accuracy Issues

NSSF Chris Cheng Pistol Accuracy Handgun Shooting Skills

When shooting pistols do your shots normally land smack dab in the middle of the target? If not, you may have some technique problems that are causing your shots to move off center. Top Shot Champion Chris Cheng has produced a good video for the National Shooting Sports Foundation (NSSF) that helps handgunners diagnose accuracy issues. By shooting 3-shot groups and looking at the pattern and location of the shots, you can see what you’re doing wrong (or right). Here are some examples. Note, this process works best for shooters whose shots fall typically in one target zone. If your shots are all over the target, your form is inconsistent and problems will be harder to diagnose.

1. Low Left — Jerking Trigger: Here we see three (3) shots at the 7 O’clock position. This shows that the shooter is jerking the trigger, meaning that the shooter is pulling the trigger too quickly and therefore forcing the barrel to drop when breaking the shot. This is a very common problem, particularly with novices who are reacting to the noise/recoil of the pistol.

2. 9 O’Clock — Too Little Trigger Finger: If we see three (3) shots at the 9 O’clock position, what this can be indicative of too little trigger finger on the trigger. And therefore with every shot, the shots are getting pushed to the left. Try moving your trigger finger on to the pad of your index finger. Also try dry firing drills.

3. High Left — Anticipating Recoil: In this next example, we see three shots around the 11 O’clock position. What could be happening here is that the shooter is anticipating the recoil, and is actually lifting the gun up when he shoots. We recommend slowing down, working on your breathing, and, again, do dry-firing drills.

4. 3 O’Clock — Too Much Trigger Finger: Finally, if you see three (3) shots at the 3 O’clock position, this can indicate that there is too much trigger finger on the trigger. Therefore when the shot breaks the shooter is pulling each shot to the right. Note: Each of these descriptions is for a RIGHT-handed shooter. If you are a left-handed shooter you’ll want to reverse those descriptions.
