Thread: CAC .303 vs HXP .303

Experience with the hxp has been variable some has been stored in less than ideal conditions.

Your nuggets of knowledge are greatly appreciated.
I don’t reload so I don’t mind that the CAC is Berdan primed.
However the corrosiveness of the primer is a bit annoying

Do you know if the HXP is corrosive?
The guncity stuff isn’t.
