I am getting into reloading and just purchased a kit from Cabelas. I looked throught the manual from Nosler and wanted to start by reloading some 30-06 cases. I also have a 25-06 and a 22-250. I was back at the store looking at primers and the man who has been reloading for 30yrs he told me and said to get a powder to start that will cover all these calibers. I bought a powder that I heard about IMR Enduron 4451. Would you reload the same grains as the normal 4451 IMR? The man also talked about fast and slow burning powders which senerio would be the best application for each? And it's tough finding a powder that covers each caliber and it seems that each manual I have Hornady and Nosler recommends different powders for there bullets even if they are the same grain. Is there a difference in powders to shoot a 150gr. Hornady vs Nosler bullet?
