Hornady LNL AP and trouble with S&B primers

[Chrossphyre]

All you Hornady LNL AP Loaders out there: I have run into significant issues using S&B LP primers in my press. Even with only two primers in the tube, the slide binds under the discharge end of the primer tube and will not come forward into the slot in the plate to enable the primer punch to seat the primer. I have cleaned and polished the whole setup, deburred the primer hole in the slide (polished that too) and basically the system runs as slick as possible until I actually put S&B primers in the tube. Then it jams consistently. No problem with other brands.


Anyone else having this issue?

Call Hornady and get support person to speak with, if part is defective they will mail you replacement for free.

Sounds like the primers are too tall. Have you measured them yet? The anvil probably protrudes above the cup more than other brands.

I've had this happen with some batches of Winchester primers too.

Does it happen with any number of primers in the tube or only with one or two? Because mine used to jam on the last primer in the tube with every brand.

S&B primers are know to not be dimensionally the same as most primers. They are known to be larger in diameter

As somebody already mentioned check to see if it does it with a taller stack of primers or a little weight on the white plastic rod that goes on top of the primers.
I've put a little over 1,000 S&B through mine last weekend.

Only use S&B primers and used 300 LP in last week with no issues in my lnl ap.

Yes, did the same thing with a 100 primer stack with a 5.56 case on the white rod. Number of primers doesn't seem to matter. I've done some research online and this seems to be a fairly common problem with S&B primers. I might have to single stage the size/decap/reprime step then switch to a different brand of primer. Sux.
