For the longest time, I've been whacking bullets out with the impact hammer. Just thought it was fine and didn't really see the need to invest in the collet puller. Well, after whacking hundreds and hundreds of rounds loose, I got fed up with it and finally decided to invest in a collet puller. Ended up with the Hornady collet puller and #4 (.264) collet. I have to say, all I could think of while pulling some grendel rounds were "why didn't I buy this thing sooner?" Best $50 investment ever that saves a lot of pain and noise. Now I have to get a #6, 7, 9, and 11 collet.
