I have some primers my dad gave me Federal large and small pistal as well as CCI Bought from Cabellas.
I normaly load in large batches 500-1000 and would use up the feds first but are odd amounts of primers so
Say I load the 9mm brass with 135fed and the rest of the 500 with cci....Would they all shoot the same or would the primers rate of ingniting the powder be so differant that cast 124tc's would not shoot the same?
Just thinking out loud here and want opinions.
