Lee Micro Disk

[Sailorman1]

Thought I would share I looked for one of these for about 6 months and finally gave up. Found a guy on another forum making one off castings of them and has them for sale. If you don't know Lee broke their mold and discontinued making them in 2012 they work with the Auto Disk system to drop smaller loads.

I bought one and it works pretty well drops a nice load for my 32 Auto.

He also sells some interesting blank disks you drill yourself for the Auto Disk. I bought a couple of those as well and they actually work pretty well drill like a dream. He even includes a drill guide that lets you know what CC hole each drill size will make.

Well hope it helps someone else.

No. You need to learn ebay speak. If it's no longer produce it's "vintage" and "rare". :wink:

Reckon what the now vintage and rare MD sitting in my loading room is now worth??????

Thanks to the OP. I'll have to pick up some of those drillable discs. I actually bought a second set of them to hone out bigger if I couldn't get the doubling up of discs to throw what I wanted.

If you drill take my advise and go just under on drill size. The first hole I drilled right on and it was just over my target load. I don't think his chart is wrong I blame my little drill presses vibration for slightly enlarging the hole. The second hole I drilled just under and sanded up with a rolled up piece of 220 sandpaper. I had to sand twice for about 30 seconds to reach my target drop. Also this made for a very smooth drop hole.

For those of you with the "Antique" MD's you might want to upgrade to his slide drop bar I see he sells those separately. It eliminates the shelf caused when you put minimal bell in the case on these thin brass cartridges. The disk won't index far enough to drop the full load. I checked out a buddies and there is not enough material in the original to file down that back edge without cutting thru the material. I wish I could do the same thing to the base of the Auto Disc I don't like how much bell I have to put in 380's to get a full drop.

Or you could make your own adjustable reduced cavity.

Jailer,
I have one of those I actually drilled and taped every hole on the A disk it still indexes fine they do not get in the way. But I have found I can only decrease the drop by .3 maybe .4 before they become inconsistent. The 30CC holes drops 3 grains of HP38 so that only took me to maybe 2.7 - 2.6 consistently. The Micro Disk is thinner and was made to drop small loads consistently.

These are drops I got in testing it with HP38:
27CC 2.9 Grains
24CC 2.6
21CC 2.2
18CC 2.0
15CC 1.6
12CC 1.3 I don't trust my scale at this level and what in the world would you load with it?

Has anyone tried to order one of those cloned micro discs?

Any way other than through Pay Pal?

I think that titan makes one that is 3d printed also

Titan does print their own and it works very well. I have also epoxied up holes in the extra set of disks I bought for some of the most common loads I use.

I haven't tested how low the adjustable auto disk charge bar goes, but I really like mine. It works much better than I thought it would.
