Jimkim, Doesn't that ruin or mar your bullet?
I use a kinetic puller and can salvage the bullet w/o any marring.
I also use the hammer type puller, but only if it's just a few rounds. Once it gets into the hundreds I break out the pliers. If the bullets are hard to pull. Break the tension with your seater. Any amount of excessive force(whether it's with pliers or collets) will ruin bullets. You have to use common sense.
