Hornady AP Press Powder Drop Locking Plate 

I bought my LNL AP back when they first came out in 08'-09'. I experienced this problem. I am a machinist by trade, so drills/taps are a dime a dozen. I drilled a perpendicular hole for a 8-32 tap size through the casting and slightly in to the bushing and tapped the frame for a set screw to make a locking mechanism for the bushing. That holds it solid and solved the problem. Hornady should have taken care of this. The retaining plate is an awesome Idea, thanks for the Aftermarket save/design.

And when I thought I was done Christmas shopping

Nobody knows the Hornady LnL better than Randall. And the tools he makes to fine tune the operation. A lot of people hate this AP because they don't know how to operate it. I just spend my time working it until I'm happy. It's not rocket science. But you nailed it just to do the fine tuning. I had a Dillon X650 along side the LnL. The LnL is set use for 9mm. I sold the Dillon to a friend of mine. I used it to do 45 ACP. The Dillon takes a while longer if I want to do caliber changes. The LnL takes a lot less time. But now I had to purchase the 45 ACP Pawl adjustment. I got the kit that has the powder lock down because, yea I have had the same problem but caught it early enough. Just a pain in the rear. No longer. Thank you Randall

Like any infomercial, the problem is being exaggerated. The little bit of wobble won't change the accuracy of the powder drops. Adding this device defeats the quick change option so it's a no-go for me, but someone that doesn't change calibers frequently might not care as much. I have had the powder drop come loose on a long run, I learned that rotating it firmly will prevent that.

A very useful tool, for powder drop trouble. I've shut off this trouble with a spring, a Inox wire and a métallic plate.

That’s awesome love the idea

That is a neat fix. But, don't you have the problem with cases tilting inwards when they index to the fifth station so that the case mouth collides with the mouth of the crimp die? I have that with both of my ap's, because the caseretaining spring dives underneath the rim of the case on the outside when the case indexes to station five, and that lifts the outside of the case a little so that it tilts inwards.. Really annoying problem.

I received and installed the red one.. Works great

These work so well.

Never had any issue with mine backing out

Could not see them in the shop. And yes, my powder measure have been lose last two years. And that is no fun.

I have a question, I definitely see the benefit of this plate, but how does it affect my ability to switch powder drop lower halves, I have one set up for each pistol caliber that I load, this looks like it had to be threaded on each time I change loads. Can it still be turned the 60 degrees needed to remove the lower half once all the dies and light are removed?

How about letting us see if it actually works. You pulled the handle and showed us the wobble before your tool but you never showed the difference after you installed it.
