I can't justify the expense of a puller, It would take a lot of pulling to ever make up the cost of the tool.

This is what I do:
1. In a press with the die removed, I run a cartridge up until the bullet is above the top of the press.
2. grip the bullet with a pair of side cutters.
3. run the ram down with the side cutters bearing against the top of the press.

It leaves marks on the bullet, no big deal. I put these bullets aside for plinking and/or making dummy rounds with.
