Hornady L-n-L Progressive Question

[jkonzal]

Can some of you guys with this press please look at the base under the primer seater and tell me if you have an indent. I have been having problems with seating depth on 45 ACP loads. I noticed yesterday that there is an indentation in the press base where the primer seater touches it. Wondering if this is normal or do I have a problem.
Thanks,
Jim

PS I plan to call Hornady today!

Yes, I have a LNL progressive and I have loaded several thousand rounds on it and I have a fairly deep indention in the actual press directly under the primer seater. I am not sure what the fix would be. Please let me know what you find out from Hornady. I have not contacted them yet because it has not affected my seating depth.

Mine has one too, but I have never been happy with that priming system (or Dillon's 650 either). My fix........I hand prime everything. I thought about trying to put down a steel feeler gauge shim, but chose to just hand prime.

You might need to pull the seater out from under the press, and clean the seating ram for the primer. You "might" have crap between the shoulder of the priming ram, and the housing for the ram. This would stop the ram from fully seating the primer (although there is a crap load off force on the ram, and I would think what ever was inside would break apart). I had the reverse problem, and crap would get between the ram and housing and inhibit the ram from returning to the origin.

I have seen the press modified to fix this. Drill a hole where the indent is and tap it. Stick a bolt in the threaded hole. Steel on steel rather than steel on aluminum. I haven't done it. I hand prime.

The dimple is pretty common after a few reloading sessions. I have a fairly large one, and it's not causing me any priming issues.

If this is actually causing your problem, there are many fixes you can google. But you can prove whether it is your problem by testing with a feeler gauge or anything thin taped over the dimple.

I just assumed that this was something that could be just adjusted out by screwing in and unscrewing out the primer pusher thingy. Is that not the case?

I have the dimple too.

My fix has been to just stick a dime over the dimple to give the primer seater more stroke.

Dunno lol. I don't know much about the primer pushy thingy . . . but it did seem easy to restore the height of the press base, ie, cover the dimple.

Spoke with a tech at Hornady. He said the primer punch is designed to only travel a set amount and is not able to travel any deeper than that. I will have to look at it, and see if I can modify it a few thousandths. I did run 80 rounds thru my single stage press to seat the primers and didn't have a single misfire.
