Thanks.Sounds good, will be slow IMHO, but safe.

Thanks!QL is not "load data", but is easy to configure for a specific application. I used 0.471" for bullet length. Please double check yours against this value as 32 ACP is very sensitive to seating depth changes.

For my Model 81 Berretta I use....
• T&B 78gr RN polymer-coated lead bullets. These are 0.314" diameter. https://tbbullets.com/bullets/polymer-coated-handgun/32-caliber/
• VV N310 and AA No.2 almost exclusively after testing 5 or 6 other pistol powders. The blow-back operation really does better with faster burning powders.
• These seat just fine in StarLine, and several other European brands of brass at an OAL of 0.950"
And shooting from supported positions at a measured 30 feet, here's some of the results I got....
► The black bull on a TQ-2 measures 2.3 inches.
Hope this helps.
Amen to that!As far as brass, my mixed headstamp 32 ACP brass was pretty bad as far as dimensional variances.
While I was at it I measured an M84 .380 barrel bore and it was .365 in.
IIRC when I checked my 92X 9x19 the bore was huge, like .375 in. Everything chronographs slow from it.
My Lee expander plug measured .310" dia.
I worked on it with 150 grit sandpaper then 600 grit. It still measured .310" so apparently it's decent steel. I'm not sure how else to reduce it without making it out of round.
I ended up using a couple grades of stone then polishing rouge just to make more bevel. Seems to have helped.If you have a drill that will hold the expander you have what is needed to reduce it. As long as the expander is spinning it will stay round. Use a steel backing for the sand paper. A file works good for this. Now the sand paper needs to be high quality made for steel wet/dry has a better backing. If you by chance have some diamond files they will work but may need to clean up with sand paper afterward depending on grit size.
Contact Lee and tell them the problem they may send you another one the right size.
I can do it for you if you Lee want take care of it. Just pm me for shipping address. I have a lathe at my disposal to do the work.
Question. Is you sizing die reducing the brass far enough to hold the bullet?
