Loading primers on Hornady LNL AP

[saltysquid]

I have heard there is a plate specifically for it also, but I have no idea what the number is.

After a little research I discovered:

My brass is fine.

Dirty primer pocket or clean did not make much difference.

The hand-priming tool easily seated the CCI 350 primers below flush.

The timing of my press is FINE.

The primer plunger is not hanging up.

The ONLY logical conclusion is that the plunger was NOT travelling far enough up to fully seat the primer.

I took a nail and cut off just under the head about a 1/16 of an inch. I then superglued it beneath the shell plate where the primer plunger rests on the frame of the press.

I found that then I had TOO much travel in the primer plunger and it was causing it too stick in up position. So I carefully kept filing down the tip of the nail until I got just an extra little lift on the primer plunger.

I just finished loading 50 rounds. With moderate pressure on priming stroke(much less force than before) I was getting below flush seating with the primers.

I wonder if on some press kits the primer plunger is just a little short causing this hard priming issue...?

Corey I just saw this post. I was still getting some high primers and was searching the forum. How is this working for you still? I noticed that the plunger will eventully wear a pit in the frame... causing the plunger to not go up as high.. thus potentially not seating the primer enough. I was thinking of taping a hardened washer under there. I have no idea how you got a nail head to work.

I will talk to Hornaday early next week and check up on this .45 ACP specific shell plate thing. Anybody who has used one please post your results.

.45ACP specific shell plate; part #392645 $37.65
You can probably get it cheaper through your local retailer. Be sure to ask for it specifically, the regular call in sales dept. didn't know what I was talking about.
Apparently they made some custom for some big name shooters and word got around. Nickels

OK, just some updating. Seems like Hornady is aware in a couple cases of issues with CCI primers like mine- only with .45ACP ironically. I tried cleaning the primer pockets and the CCI primers seat much better (albeit not a good solution for an auto indexing press). I also tried using WLPs and they also seemed to work much better- even without cleaning the primer pockets.

Hornady seems to be still working on this but for now I'm going to try more with WLPs like Shoney suggested.

I have the same issue with 44 magnum loads
I changed primers to Federal and they fit easily. The CCI large pistol primers are a bit more difficult to seat flush.

Perhaps a longer lever on the press may provide more leverage.

The sharp point on the primer punch will eventually put a dimple on the press which is not good, they should put a steel insert and make it adjustable. A 1/2" hardened steel bolt would be perfect and make it slightly adjustable.

Resurrecting this thread because I have same issue...

Resurrecting this thread because I have same issue... 2.0

So, my LnL was doing fine, no primer issues - then the primers stop appearing in the shuttle. Took the whole tube and primers apart to inspect and found out 2 things.

1. If you loosen the mounting screw that holds the top of the wire (the plastic bracket hold down) - there is some play. So I ajusted it out so the shuttle traveled a bit further down its slide.

2. If you remove the shuttle, turn it upside down the insert one end of the primer tube - then flip the primer tube and insert the other side - it will seat to a different depth (at least it did for me). Seems the side taht doesn't insert as far would have more wiggle room, possibly for a primer to hang up? Anyway, I marked the better end of the tube ( the one that seats deeper) and I make sure that is the end that is toward teh shuttle. All of a sudden, the primers are flowing again.

"One more reason to prime seperately. "

Yup

Also, when I prime - some primers seem to farily effortlessly slide up into the primer pocket.

Then, other times - there's quite a crunch as an edge of a primer isn't probably dead center (I'm speculating) - but it seats. Point being it didn't seat smoothly.

Why the difference?

Next time you have the feed tube out look at the ends, one end is machined to fit in the opening of the primer assembly.

If the primer shuttle area on the base plate gets powder or other debri ( cleaning media ) caught in it I notice the primers don't line up and have crunched a few. Clean out the shuttle area and everything is fine again.

Also had issues initially with .45 acp, worst problem,Tula then CCI and none with Federal FWIW.
No problems with small pistol primers including Russian cheapo's.

LNL primer set up is very sensitive to tension of the associated screws and tubes used....tight is bad!

If your are not in alignment the dwell time is not allowing the primer to drop. If you find that it works with a full stack of primers and as it gets lower you start having problems use a brass pusher rod. The extra weight shortens the dwell time needed for a primer to drop. The pusher rod that I use has a small primer cap on one end, larger on the other. The spent caps are epoxied to the rod. This corrected a lot of feeding issues when I went to the heaver rod. I normally install it when the stack is down about 1/2 way.

If your still having problems try using a paper shim (0.003") under the primer base. If this works you will need to sand the base a little with 600 grit on a block of wood or steel to keep it flat.
