Hi, new to reloading. Can't find magnum primers for my 300win and 300Wsm. Is their a substitute ?
Thanks, Gary
Thanks, Gary
I also read the 34 is just the harder cup and not the magnum compound, too much info on the internet sometimes!You might research the CCI 34. The cup is harder and the primer compound is the magnum cci 250 compound from what I’ve read.
