I found load data for my 9mm..... One manual has the exact bullet weight, but uses Winchester WSP primers. The other manual has a load for a slightly lighter bullet, but uses CCI 500 primers (which I have.)
I know the primers are the same dimension, but are they truly interchangeable? I would think I could substitute the CCI 500 for the WSP, but would like to see if you guys know something different.
thx
