Lee Challenger with Uniflow

[Boats]

Someone (maybe someone here?) told me about an adapter that allows a Uniflow Powder Measure to mount to a Lee Powder Through Die.

I found the beast on eBay for a few bucks and bought one, even before I had bought the Uniflow.

Yesterday I got it all together, put together the Uniflow with a large micrometer attachment, and went to bed.

Today I mounted the Challenger on the bench, and the Uniflow on the Challenger, and everything seems to work fine. I did a bunch of powder drops with the little bit of RL-15 I have, and was able to quickly calibrate the Uniflow to drop a consistent 24gr of powder.

Then I actually tried it with some .223 brass in the press, and it at least minimally puts powder in the brass.

Unfortunately, I don't have any IMR 3031 on hand to do some real testing. Tonight after work I'll go buy some and try to build some .223 rounds in batch mode with the Challenger.

Here's what it looks like so far:
