well i had primed 70 brass cases,different brands,all primed no problem except around 20 brand new factory Hornady cases that had been fired one time and i was going to reload these with the others,i have never ever had a case refuse to except a primer.Other hornady once fired cases primed just fine..
The primers were new in the pack cci 400 and all were the same size...no mix ups.
should i use another type primer?
I have used the cci 400/Hornady brass with great success before and my powder charge is no where near max...what "could be the problem"?
