For many years, I loaded 9mm, 40S&W and 45ACP on the Pro 1000.
I had the dies preset on separate turrets and to change from 9mm to 40S&W, it only required the turret/dies and large case feeder/bent Z-bar swap. It takes me on average about 3-5 minutes.
Cost? This is excluding dies:
9mm to 40S&W - (3-hole turret
$7.50 + large case feeder
$19 + and bent Z-bar
$2 = $28.
9mm/40S&W to 45ACP - Shell plate #2 $15 + 3 hole turret $7.50 + large primer feed attachment $12 + large case feeder $19 + large case slider $7 + bent Z-bar $2 = $62.
You can also buy another complete shell plate carrier to speed up the caliber change - Shell plate carrier/shell plate/primer feed attachment
$39 + 3 hole turret $7.50 + large case feeder $19 + large case slider $7 + bent Z-bar $2 = $74.50
Now, I have 2 Pro 1000s set up (1 for 9/40 and 1 for 45) and have almost no downtime switching calibers. Classic Turret is setup for .308/.223. and still have a single stage for load development/resizing duties.
