I have the Lee Breech Lock Hand Press with #1 universal shell holder for 38/357 and Lee decapping die.
I use it solely to decap spent cartridges.
It is very, very well made.
Operation is smooth and flawless, with very little effort required to pop the spent caps.
The cap falls down into the ram cylinder, and collects there.
When you are so inclined, hold it over the trash and dump 'em out.
No spent caps falling on the floor.
This is wonderfully mindless while watching TV.
