Here's a potential weekend project for the more adventurous. This is my Lee PPM. I made the modifications a couple years ago, and I shared it on another forum. I am thinking there might be more interest over here?
The changes:
1. PPM lapped for smooth operation and no leaking with almost any powder
2. Quick change metering inserts. As many as you want to make for less than a dollar apiece.
3. Custom powder drop tube that works down to .223 without spilling any powder.
4. Drill press stand, infinitely adjustable for height to just barely clear the casemouth.
5. Screw-adjustable amount of up/down travel on bearings, in order to get the powder funnel to drop and lock on to a 223 case mouth in a loading block for no spillage.
Lapped the measure with a drill, using a custom jig:

Cut off the end of the meter with a hacksaw, for transition to quick-change metering inserts:

A magnet is epoxied to the metering tube to secure the quick change inserts:

Creating inserts with bolt, washer, nut, and a piece of dowel. The washer is soldered onto the bolt. The nut locks the meter in position.

I made up a handful of these, some with different lengths for covering overlapping ranges.

I also created one much fancier insert with a much greater range of adjustability.

I removed the funnel and replaced it with a modified 223 case. The case is too big to fit. This is good. Since the inside of the plastic tube has to be milled larger to allow the 223 case to friction fit, there is no "shelf" on which powder can trap. I sized the case without expanding it. Then roll-crimped the mouth before cutting off the casehead. This way it locks inside of the mouth of a sized and expanded 223 case. And it easily fits over any larger caliber with no spillage. I mounted it on a drill press stand, so that the height is adjustable.

Using some epoxy and brass tubes, I fashioned a sliding-bearing so that the entire measure can move freely in the Z axis by a fraction of an inch. This allows you to lift the meter and then drop it over the mouth of a 223 case.

Here's a video of it in action, BEFORE I modified the meter. You can see the original meter in the video. The new quick-change inserts are flush with the end of the shorter tube and allow plenty of room for maneuving the loading block.

I've loaded thousands of rounds of 223 with H335, without losing a single flake. Hope you guys like it. Carry on.
