There are several reasons why I don't use a kinetic puller, and these are just a few of them:
1) Potential bullet deformation
2) Potential primer ignition (not from puncture, but from residual impact)
3) It is made of thick plastic, so they will eventually break
4) Noisy
5) Messy (powder dumping out)
Out of the 5 possible results listed by MudRunner , 4 have happened to me while using an inertia hammer Kinetic bullet puller . #1 , potential bullet deformation has NOT happened yet , as I use 1 or 2 foam earplugs in the bottom of the hammer tube .
# 5 , yes the powder dumps .
# 4 , quite noisy .
# 3 , I have broken 2 , so far .
# 2 , You have not experienced an adrenalin rush until you have a Federal 215 primer ignite on top of a .300 Win. Mag . loaded with 77 grains of H1000 .
EVERYTHING went into SLOW-MOTION , as I watched the primer lift out of the primer pocket , looking much like the NASA Lunar Landing Craft of 1969 , with a jet of flame blowing from it's cup , as it shot by my face , going upward into , and nearly through , the sheetrock ceiling in my garage , as I was wildly throwing the hammer out the open door . I think that the only thing that stopped it from achieving orbit was that it buried into the lower edge of a 2" x 12" beam in the attic .
When this happened a second time a few months later , I retired the Kinetic hammer .
