Does any body have a hornady data manual and does it contain any data for a load for the 7x65r using a 139 or 140gn bullet and IMR 4831 powder? Also can H4831 be substituted for IMR4831 powder?
And a simple question, with new unprimed cases do I need to run them through a sizind die first?
Many thanks
