Just got one of those cheap kinetic pullers from that BAY place. Don't bother. The rim of the collet is too thick to grip the case properly and 90% of the time the complete round pops out of the collar (Like wot that feller said about equal and opposite reactions)

The one time in 10 that the bullet actually gets pulled the case does a Superman (Leaps tall buildings).. equal and opposite again, lighter (case only) so goes much further.

I borrowed one of the good old boys and of course it worked perfectly.
