Hornady lnl primer feeding too lowl

[Hamburgler]

Hey,all ,in my quest to seat primers lower i followed another bit of advice and cut the spring on the punch,along with having a spent primer underneath it seems to seat slightly below flush,although with some decent effort on the handle.

Im still going to work on this prob to get it lower and more consistent tho.

Hamburgler - After 26 posts, we still don't know what type/brand primers you're trying to seat. Please share because some primer brands such as Wolf or Tula are known to be a little oversize and may have more difficulty seating fully in newer brass.

My bad,im loading 9mm,with cci 500 small pistol primers in once fired winchester brass

I have a new LNL with perhaps 2K loads thru it that has developed the occasional high primer condition. Careful examination revealed two interesting things. The priming pin is driven at the bottom of the downstroke by the bare cast aluminum (soft) of the press body. This may be okay some of the time, but is not good. My primer punch comes almost to a blunt point on the bottom. The flat is not much more that 1/16" in diameter. This appears to be a simple case of over beveling the end, and there can't be any reason for it other than a machine setup problem. The result is a fast developing dimple in the casting, which accounts for the loss of adequate lift.
I'm going to make a new flat bottomed pin, and machine a small steel base to install in the casting. Fortunately I have the capability to do this.
Otherwise, I'm more than satisfied with the quality and function of the press, but Hornady should address this if the problem is widespread.

BMB, It sounds like you were not fully seating the primers. The most common source of the problem is the shell plate loosening up. I have over 20k through mine. Do a quick check, put a empty deprimed brass in the shell plate (priming station). Push the handle all the way forward and see if you can slide the brass out of the shell plate. If you can you have a problem other wise it's operator error.

Don't be shy about seating the primers.

Guess you didn't read my post. If the primer punch will not lift high enough it doesn't matter how hard you push the lever. And no, my shell plate is not loose. This is a real problem that obviously SOME of these presses MIGHT develop, as this thread attests.

I did read it the reason I responded. But you still did not say how you determine yours was not seating them.

I have 10x as may rounds through my press as yours with most all 9mm, SPP. I was just asking how you determine it was not enough. Since you mentioned some were not seated deep enough, NOT ALL. The method I posted will tell you whether the dimple in the base is causing problems. It may or may not.

There is nothing wrong with putting a washer or any thing hard for it to contact. I talked to Hornady over a year ago and they did recommend putting something hard and thin so it does not impact the free base height. But if you use something that has some thickness you need to also apply the same thickness to the base lift spring, ref spent primer tube.

They may have changed or have a lot of the primer seaters which may be out of spec. You said yours was 1/16", mine is larger than that and is domed not pointed or flat.
