Like others have said regarding kinetic pullers

put a foam plug in the bottom
bump the bullets down a several thou into the case with a seating die
use a hardwood endgrain, or a big chunk of lead. that tiny bit of give saves your puller

I made one using PVC and it works good
I also made a homade Grip-N-Pull years ago with hardwood. didn't work too well. (gonna try that one again, but using grit embedded into the wood hole for grip)
So made one with steel. worked good

Next time I get a "rountuit" ima use thin pieces of leaf spring to make more G-N-Ps for each caliber, so I can have the hole very near the end for max leverage
