Lee Autodisc for Small Charges

[Tex1001]

Now, do you guys like a roll crimp or a taper crimp on 38 Spl?

All of my cartridges requiring a roll crimp use a Lee factory collet crimp die. Much more forgiving of small differences in cartridge case length.
I altered a 357 collet die crimp length spacer for 38 special, 44 magnum to 44 special, 45 Colt to 45 auto rim, etc.
Outstanding collet crimps for 30 Luger and 7.62x25 cartridges.

I did find a guy making a reproduction of the Lee Micro Disk. I have no relationship with this seller.

I've loaded the charge of Bullseye you list with the auto disc but to be honest the auto drum does a better job with that load for me. I'm using a Lee classic cast turret press. The auto disc seems to do it's most accurate work with charges over 4 grains using the adjustable charge bar. Set up that way the a-disc works quite well. On smaller charges, not so much.
The auto drum is the way to go for what you are wanting to do and they don't cost all that much. IMO

+1 on the Auto Drum. The Auto Disk doesn't work very well in 38 Spl charges of 2.5-3.5 grains, especially with flake type powders such as Red Dot & Bullseye. You will get "bridging" and wind up with a bullet stuck in the bore. I tried the Micro Disk, but it is meant for smaller charges of less than 2 grains for 32 and even 25 ACP cartridges. It will work if you use Titegroup which is a ball powder. I switched to the Auto Drum and never looked back.

My understanding is the Lee Precision Micro Disk disk molding equipment was burned in a fire and never replaced. I have one and it works great for small charges.

This company is very easy to deal with and makes a nice copy of the Micro Disk.

Leaks Powder

Mine leaked powder to a thinly broadcast layer over Pro 1000 and bench, but this was the least of its problems. My Auto Disk was the old, all pot metal version. Newer ones are likely better. Don't know if they have sliding lip seals like a Mec shotshell loader bar. Die mis-alignment, primer feed jams and broken index gears kept me busy, so I didn't fret too much over the powder measure. I never trust any powder measure, rotating drum or sliding cavity, to not bridge powder in the drop tube. I insist on eyeballing every charged case. The Auto Disk in a Pro 1000 has the advantage of riding on a shaking platform, gaining the same safety advantage of measures with a rapper. Gave the whole rig away for someone else to enjoy tinkering and tuning. I may sound like a Lee hater, but I'm not with lots of their stuff, good and otherwise, but I would never use one of their progressives expecting to save time over a single stage rig. The Auto Disk would be the most reliable part of a Pro 1000.
