At the range yesterday I was sighting in my AR with a new batch of reloaded 223, which I'll list below, and randomly I had 3 misfires. I pulled the trigger and only heard a click. Kept the gun pointing down range after each and after a few minutes safely ejected the rounds and inspected each one. I set them back in the box and tested a few more rounds and they all went bang. After I got home I used my lyman puller to remove the bullet which took extra effort and but once the bullet fell out no powder fell out. The bullet had black residue at the base and the case was empty. The primers all seemed to have a legit strike. After reading through a few posts I am not sure what the cause is. I've reloaded over 500 rounds with this same load and I really don't know what happened.
Gun: AR-15
Bullet: Berger 77gr
Powder: RE15
Primer: CCI Mag no 450
Brass: Once fired mixed
Reloading Steps:
Hornady Sonic Cleaner with their solution
RCBS case lube pad
RCBS re-size / de-prime
de bur cases
clean primer pocket
one more round through the cleaner and dried
RCBS Priming hand tool
added powder pressed bullet
Same steps I've always done.
