Did I catch a possible accident?

I have only shot a few of the first rounds I have made of 223 . The primer was pushed twice and has a mark accross it. I am sure it is due to me not knowing the proper technique of hand priming the right depth the first time. My questions is this. If I ran this amo through my AR, would this be a lickly candidate for a slam misfire fire? Maybe not so much on the bolt action? Should I dissassemble, reclaim and start over?

Sounds fine. There is only so far that the primer can seat. As long as it doesn't appear that it was pushed in so far as to crush the primer cup.

The primer was pushed twice and has a mark accross it. Pushed how? Hit by the firing pin on pulling the trigger? Or pushed by the bolt face on chambering a round? A high primer is never a good thing.

It looks like the moon when it is 3/4 full. A line going accross the primer. Doesnt look fractured. Just a indent line. From when I hand primed it. High enough I didnot like it so I pushed it again just not directly in the center.

As long as it is seated squarely at or below flush you should be fine. A high primer (one seated above flush) is considered more of a cause for concern/slamfire.

It looks like the moon when it is 3/4 full. A line going accross the primer. Doesnt look fractured. Just a indent line. Ok to fire. When i seat primers in crimped military brass , sometimes i get a little piece of shaved brass laying in the seater plug. This makes a line across the primer like you describe.

I wouldn't fire them if I thought the line was actually a cut all the way through the metal of the primer. Other than that they should be fine.

I've fired several that have had a light line impressed due to a piece of shaved brass in the primer seater leaving a mark. The rounds fired as expected, were safe, and the line disappeared after firing! No problems.

I check all my primers after seating and if I see the mark I check the seater, fish out the shaved brass, and continue on my way.

Good Luck

While the AR can slamfire because of its floating firing pin, it is one of the safest of such designs due to (1) the lighter firing pin weight, and (2) the degree to which the bolt has to rotate in locking before the firing pin will protrude from the bolt face. (Pull the bolt out and push the firing in forward while rotating the cam pin by hand to see what I mean.)

That said.....

Take a look at the top of priming tool's seating rod (that pushes the primer into the case pocket) and see if it has gotten a sliver of brass sitting/smashed on top of it. If so, remove it w/ a bore brush and press on.

If that's the extent of your problem, you're fine.

BREAK BREAK:
Seat primers all the way home/until they firmly "stop". With [recommended] hand-priming tools it's near impossible to apply excess pressure, and relatively difficult to 'over-gorilla' it. After a few dozen, you'll be fine in judging what's "normal" and what's "different" to the point of stop/checking for a problem.

As to proper depth, it's pretty much where the primer automatically stops. Lay a metal straight-edge across the case/primer and you should see a bare sliver of light where the primer is just under being flush.

It's not unusual for the priming arm to make a mark on the primer if everything isn't squared up while seating the primer, but as long as the primer is fully seated (A bit below flush) you will be fine.

My RCBS hand primer can do that even though the face of the rod that seats the primer is smooth and square. All it takes is for the primer to be canted a little when the primer starts to enter the primer pocket.

I would take a look at your priming process and the face of the priming plug to ensure a better job of priming in the future. No big deal. :)

Ammo is ok to shoot. This explains where the mark came from.
