I have and use a hammer bullet puller.
When I took an NRA reloading course the instructor told us we were human and humans make mistakes. We should get a bullet puller as a basic part of our reloading kit. He stressed that it is very important to pull your mistakes rather than try to shoot them.
He also gave us some advice. Never load more cartridges in a single batch before trying them at the range, than you are willing to pull.
For rifles I load at most 50 cartridges at a time and then go to the range and shoot say 10 to 20. For handguns, I may load 50 to 250. I have had to pull about 50 handgun rounds once, when a powder manufacturer posted the wrong information on its website. Always work up your loads, always!
Most often I will have a problem with crimps or something that I decide I want to pull the bullet, resize/deprim the case, reprime the case, bell the mouth, load powder, then re-seat the bullet and crimp it.
A friend of mine was given about 200 rounds of handloads that were way too hot and resulted in hard extraction form his revolver. He borrowed my hammer and spent a day salvaging bullets and brass. I reloaded all of his brass with loads I had worked up for him.
