Winchester LPP
Magtech once-fired brass
4.5 gr. HP-38
Remington 230 gr. FMJ
1.265" OAL
I tried to get the load to 4.2 grains (the starting load), but the Auto-Disk didn't want to go there - it was either 4.1 or 4.5, and I didn't want to go below the published minimum. With the max load being 5.3, I thought this was a good starting point.
Not all was sunshine and puppies, though. I think I need to adjust the expander die a little bit, because a few of the bullets were hard to seat - the edge of the jacket was getting caught on the rim. The Lee instructions say to screw it in until it touches the shellholder, then back out one full turn. I think I may need to use only a half-turn. Thankfully, though, I only had one of these:

That's one reason I wanted to start with FMJ instead of lead - I knew something like this would happen. Recovering the primer was easy enough - just ran it back through the decapper really slowly with steady pressure and it popped right out.
It looks like I need to add the adjustable charge bar and a riser for the powder measure and I'll be just about ready to go into mass production. Thanks for all the hints and tips, everyone!
