I've started reloading for my 7.62 X 39. I'm using the Hornady 123 GR. Interlock bullets on new Prvi brass with CCi primers. My problem is the shortage of powders for that load. I have the H335, but I'd like to try some IMR 4198 or Reloader 7. Budget Shooter Supply (whom I love dealing with) has both of those in stock according to their web site. Any thoughts or suggestions?
