I have a Cabelas collet bullet puller, It works well, but my main complaint with it is, it comes with 4 or 5 different collets and there is nowhere to keep the other collets when not in use, the handle is hollow, I dont know why they didnt make storage space in it. If one of my buddies borrows it, I have to give them a baggie with the extra parts in it too, (just one more thing to lose
) as far as denting your table, I have a rug in my basement, I just whack the rug, that on top of my concrete floor, works great.
