I just bought this rifle, its a 308, and has a 18", 1:10, 5-R barrel. I was wondering where to start with loads. Hmmmm, so many choices....I have 175SMKs, LC brass and most powders. Any help would be appreciated!
I have not loaded for or even seen a M&P10 yet but I do know I like IMR4064 for loading .308 ammo. There are a bunch of good powder for that cartridge but that's the one I find most accurate.
