Up until last Sunday, I had always used an old RCBS kinetic puller, or the Lyman for 338LM.
Sunday afternoon I was cleaning up the reloading area and came across ~250 rounds of various "test" ammo I realized I'm never going to shoot, so I decided I'd pull it all down.
I went and purchased the Hornady collet puller, and damn, that is the ONLY way to do that job. I've ever pulled down 30-40 cartridges with a kinetic puller and it works, but sure is slow and noisy. The collet puller makes the job much, much, much better.
The kinetic puller is good for one-sies and two-sies type work, but if you need to pull down some ammo, you really need the collet puller.
