To get the best performance from a kinetic type bullet puller it needs to be struck against something that is hard and unyielding. I find my concrete floor works well. Second choice is the anvil on my 45# bench vice.
Anything that absorbs energy compromises the shock the puller needs to work right.
Other subject: after trying several, I l like my Hornady collet puller.
