I just got my new Hornady LNL setup and I am not sure if I have an issue with the powder measure or not.  When I drop powder I have the rotor activating the entire way to the top of the rotation, but when the rotor comes back down it doesn't rotate to the bottom of the powder measure.  I am able to push the rotor down just a little further.  I don't know if that small amount of movement will affect the amount of powder dropped or not.  I wasn't able to measure a difference with Bullseye, but I just want to be sure.

Loosen the clamp on the powder measure(the top one) and move the powder measure up about as much as you think it needs to go for it to come all the way back down by it's self, once you get that part set and back tight then loosen the bottom die lock ring and readjust the powder measure in the LnL bushing to where the rotor moves all the way up(but doesn't bind at all) with a case in the shell plate. Now when you go to charge a case there should be enough room for the PM rotor to freely move all the way back down.

This has to be done for rifle and pistol each time if you want it perfect and is why most of us have a complete separate powder case activated drop linkage kit for each, one setup for pistol and the other setup for rifle, this way all you have to do is swap the powder measure from to the other real quick and your ready to go.

Thanks, I'll give that a shot.

Check your linkage for any binding.

I had to have them send me a new powder measure due to a bad casting.  The rotor didn't quite rotate easily enough. I called them and they promptly sent me a new one with a new rotor.  The cool thing is that I took the old one and reamed it out enough to make it work properly.  I now have 2 powder measures, 3 rotors and 2 rifle and 2 pistol stems.

At any rate, check to see if the rotor is binding or showing wear in any one spot.  Probably just a tight fit.  I used a drimell tool and the sanding drum to ream it out a bit.  Mine was really really tight to.

That took care of it and now my powder dispenser has a full range of motion.  I double checked the manual and it didn't seem to spell out the adjustments, but it's fixed all the same.

Make sure you clean and degrease it very well, or it'll drive you nuts. Are you loading rifle or pistol with it?

I'm loading pistol at the moment while I get the hang of moving from the Lee Classic Turret to a full progressive.  I broke it down and cleaned it per the Hornady 12 part YouTube series.  The one issue I do need to resolve is the Bullseye powder sticking to some of the cast parts, but I think a couple of dryer sheets may fix that.  

 

Try the powder thru expander from www.powderfunnels.com. It's a great accessory.
