with my puller the primer is towards the ground/bench

, not sure of what puller your using, but this is the first time of heard of this happening,
What if this was a live round that I wanted to break apart? I am seriously thinking about not using it anymore. Has anyone else ever had this happen?
, live round or not a primer is very dangerous, were you wearing safety glasses[:-], the reason i ask is i had a childhood friend do something very stupid and he lost the use of one eye
