Sorry no peek-tures, the camera is dead atm.

Just inspecting a fresh run of 9mm (115PLRN, 5.5UNQ, starline +p) and I found a primer that my new SDB had seated SIDEWAYS, then crushed all the way down flush.

1, never seen that happen before

2, how it didn't KB, is a flippin mystery to me.

I think I'll call that a night and clean that machine out tomorrow.

Now you know why I sold my SDB. Had more problems with the primer system, but it was an older one. I understand they have fixed the problem, sort of.

I don't know of any primer seater, installer or aperatice that won't put an occasional primer in sideways. As far as setting it off...It takes a SHARP strike to do that. Over 20 years and countless upside down, sidways and crushed primers and not one has gone POP...I just punch them out with the resizing/decapping die and start over...

Seating of the primer sideways is a common occurence with Dillon presses, my 550 does it a high percentage of the time unless I am very observant, thats one of the reasons I use it only as a secondary press.

Primer compounds will not detonate unless it is subected to rapid crushing against the anvil or other solid object. I have crushed many primers sideway. quarter turn, shaved off the the sides, and so on, but in more than 47 years of loading, I have never detonated a primer in the press.

I feel that I need to defend my Dillon 550B press regard operation. I run two of the Dillons, one is set up for small primers, and the other for large primers, otherwise both are the same. My first 550 is over twenty years old and I have yet to have either press drop a "sideways" primer. Truthfully I have had an occasional up-side-down primer, but blame that on operator error, not on a mechanical error. If a person is getting sideways primers. I would seriously review my primer loading procedures before faulting the press. Progressive pesses are like computer programs: garbage in= garbage out!:cuss:

In 12 years and close to 100,000 rounds, my Dillon 650 has never put a primer (large or small) in sideways; and backwards primers have been completely eliminated since I got the RF 100 automatic primer tube loader, about 8 years ago.

I've crushed a few primers by trying to stuff them into an undersize pocket (my error) - but none of them went "bang".

In fact, last Tuesday a round didn't even go 'ffffft.'

Dropped the mag, waited a little while. Ejected the round--the primer was in backwards. This was a .45ACP round I built in 1992.

Because I now prime on my Lee Turret (updated to 4-die)--in the normal sequence, not as a separate activity--and that machine primes on the first stroke / downstroke, the feel for primer insertion and seating is exquisite.

The '92 round was loaded on a Pro 1000--which has less feel (because of the multiple cases in process), but still primes on the downstroke. Obviously, my inspection techniques then (and now) were somewhat lacking.

However, I have never had a primer detonate--but then again, I've really only used Winchesters. They've been absolutely reliable and have worked fine for my pistol cartridge production.

How are you liking that btw? I've been looking at them lately, seems handy but a lot of money for the convenience.

I don't think the Lee Classic Turret will. You can see the primer before it is placed under the case and seated. If you had to you could turn one very easy before it was put in wrong. In the thousands of rounds I have loaded on my Classic all of the primers have been in the correct direction.

I've had many sideways primers over the years. Crushed flat like yours. None have gone bang on me. Others are right here in that it takexs a sharp strike to set one off.

[FieroCDSP]

The priming setup on the Loadmaster can occasionally flip them. Upside down isn't a problem like sideways. That'll just jam up the machine.
