avoiding high primers

Field · October 26, 2009, 12:21 AM

I am using a hornady LNL AP and loading 9mm, sometimes I will produce batches of ammo where some of the rounds will have primers that are not seated deep enough and wont go off when it by the firing pin, the primer seating action with this press where you are pushing the lever you get a good feel for if primers are seated properly or not though because i use various jo blow brass that i pick off the ground not all of them feel the same when being seated. I really dont want to go hardcore and try and use only 1 type of case that i know for sure is going to work because i have not yet accumulated a good supply of cases anyways.

If any of you have ran into this kind of problem with primers not seating properly, how did you resolve the situation? thanks.

Not meaning to be flipant here, but in order to give clarity of your thoughts, could you please punctuate your sentences.

I also load on the LNL AP and a 550, and I also noticed the same problem on each press. I segregate out my cases by brand and load them. I may load 3 or 4 different brands in the same run, but adjust my priming pressure according to the desired result with each brand of case.

Good Shooting!

I load 9mm on a 550b. You can develop a feel to the primer seating on the upstroke if you are attentive enough to the operation of the press. Not sure how the LNL primes, but would think a similar feel can be developed.

And, +1 to Shoney's post.

One thing you can do is deprime all your brass and clean the primer pockets. Lee makes a cheap tool for this or you can use a flat blade screwdriver.

As others have said, easy solution... segregate your brass by headstamp.

James R. Burke · October 26, 2009, 07:36 PM

I segregate by headstamp, and do it seperate by hand. It is one more step to slow you up, but I know it is seated correct. Also check them before you try to shoot them.

We were running into that occasionaly to, and we had to start cleaning pockets about every 5 or so times, so we would trim at the same time to just to get even seating and crimp. Shooting LR primers from a 45LC because of heavy bear loads caused us to clean the pocket after EVERY firing until we uniformed the pockets to LR depth.

What brand of primers are you using? I had this issue with CCI primers for every caliber on the LNL AP. No problems with Winchester, Remington or Federal.

Field · October 27, 2009, 09:06 PM

CCI of course

impactco · October 27, 2009, 09:16 PM

Try an alternate brand. I'll bet it will solve your issue. It did for me. Let us know.

Field · October 31, 2009, 12:28 PM

i need to get one of those tools (whatever its called) that flips all the primers right side up so you can suck them up with your primer tube

CCI primers seem to cause moreproblems in progressive presses than other brands. When I get high primers, I re seat them with a Lee hand primer. Yeah, it's probably not wise,maybe even dangerous, but I do it and do NOT recommend it for others.

PBKing · October 31, 2009, 07:47 PM

Segregate you brass

floydster · October 31, 2009, 08:30 PM

Seat the primers like you mean it, I load on the LNL ram the damn things home,
How many threads do we have to have on seating primers, there is only one way, man oh man!!!!

rdmallory · November 1, 2009, 03:58 PM

I seat all mine by with the RCBS tool watching Mythbusters on TV. Doesn't take long and yo can tell if one does not feet right.

mongoose33 · November 1, 2009, 05:04 PM

I have the LNLAP, and when I am seating primers I give the upstroke a little extra oomph when I push that primer home, almost a double push to the handle.

floydster · November 1, 2009, 08:30 PM

mongoose33, you have it right.

Field · November 2, 2009, 10:07 AM

yeah ive just been starting to toss ones that dont feel like they are seating right so i dont have to deal with them again
