I just ordered all the reloading equiptment I need to get started except the Hazmats. I am going to the local guns shop this weekend to pick up some powder and primers to start loading my ruger international .308 (just to get my feet wet) and wondering which powder would you sugget for a .308 carbine using hornady 150gr btsp bullets. I know I need to try different bullet/powder combos but what would be good to start with. Also keep in mind I may later decide to switch to lighter bullets. Thanks for any suggestions.
