I have a question on reloading some rounds for my 300 Win Mag (Hornady interbonds, 165gr)... Attached is a picture of a page out of my Speer Reloading manual. Im new to reloading so I don't have much knowledge on this.
So my question is, what would be the advantage of using Reloader 22 or H4831SC compared to using the IMR 7828? Why would I not use the IMR powder and get the extra 200FPS? Would it be less accurate? And why is there more powder per shell? Is it shaped differently?
Also, is this data for Speer bullets ok to use for my Hornady bullets?
Thanks!!
