Many folks don't like the noise associated with impact bullet pullers (hammer style), and I didn't like banging mine on my bench. So, I have an ingot of fairly soft lead, 4"x8"x1" that I use for an anvil. The lead deadens the noise, but does not soften the blow enough to hinder bullet movement. I also occasionally use a Lee Loader when I feel "retro" and the lead anvil makes that process quieter too (and it's easy on the tool too)...
