I have a cheap single Lee press I use for small operations like this, so it made it a little easier.
The inertial pullers last much longer if you hammer onto a piece of wood, on the grain end. A piece of firewood or chunk of 4 x 4 works well.
Try putting one of those high density foam earplugs in the bottom of the kinetic puller. They absorb the impact of the bullet without deforming it.polymer tipped bullets can be easily deformed when the bullet hits the wad in the internal cavity.
Finally got the die and collet. Works like a charm! Very intuitive to use. Doesn't deform the bullet either. I'd buy it again!
