Thread: Fed large rifle

Ah, the old bare fingers
You would have to be oozing great dollops of human oil (or whatever humans ooze) to kill a primer and even then it would take some time.
I have soaked primers in oil to kill them and they still went bang (frighteningly so) at seemingly full tit when tried next morning.
Even soaking them in water doesn't kill them straight away.
Alcohol which would maybe disolve the seal over the priming compound may be more rapid.

More likely a primer seating problem - maybe even a combination of too deeply (crushed) seated and excessive FLSing (if OP FLSed.)
Or not seated down onto the anvils.

OP - photos of the strike will assist in most cases.

Also have you stripped the cases and removed the primers to check they haven't partially gone off?
I had this happen once in several thousands of rounds with a CCI primer.

Federal primers are pretty damn good. The only brand I won't use now is the goldie coloured Winchesters.
