Hi all, I started reloading this year and I'm using a Hornady LNL AP with the Case Activated Powder Drop.

Works well but it's kind of a PITA to change caliber right now with only one powder measure. For instance, last caliber change (9mm -> 50AE), in addition to changing the sizing dies, bullet dies, shell plate and priming insert, I had to do this for the new powder:

  • Remove upper assembly with hopper and empty powder (hard to remove all the powder)
  • Change rotor and metering plunger from pistol rotor/pistol metering plunger to rifle rotor/standard metering plunger
  • Change powder sleeve in the lower assembly die
  • Put back together
  • Re-screw the powder drop die to the correct depth to operate the powder measure correctly because the new powder sleeve has a different length.
Note: I don't use the Hornady PTX expander for 9mm, I use a separate bell/flaring die

I want to ask someone who does frequent caliber changes with the LNL AP what is needed to do quick changes of the powder measure. Right now my best guess is that I need:

Then all that's needed when changing caliber would be to swap the powder measure. If I change the powder sleeve (say from pistol caliber to rifle caliber), I also need to re-screw the die to the correct depth. This last part sucks, but to avoid that I think I would have to buy the full lower assembly again (https://www.titanreloading.com/product/hornady-case-activated-powder-drop/), so I can swap the whole powder measure + powder drop die in one go. That's expensive and would take a lot of space... Still, I'm curious to know if that's often done.

Am I on the money or did I miss something? Thanks.

I use the LEE auto disk on the five Projector presses that I have . Inexpensive to buy ,case operated easy changeover no extra linkage to fuss with and the powder drops are on the money. The Hornady measure set up sucks.
 
I purchased a second powder measure.
This way one has a small rotor for pistol while the second has the large rotor for rifle.
You need to purchase the case activated powder drop #050073 so that the powder measure works on the Hornady LnL AP.

Now you have 2 complete powder measure assemblies that fit on your press.

I do my expanding using the PTX expanders that go in the case activated powder drop so I buy a quick change powder die #050074 for each caliber and mark them as such with the appropriate expander die inside of each.
I also buy a PTX Powder Measure Stop #290049 for each caliber.
