Re: Reloading for the AR10
Same data should apply, just make sure you're using powders suitable for the gas operation of the action; basically mid-range burning speeds such as 4895, Varget, and yes, RL-15. You should heed the advice to back down if you're using military 7.62mm brass, as it is a bit thicker than the commercial stuff. It's also good to use in autoloaders, since it's made with gas operation in mind.
If you haven't loaded for autos before, they're different and need to be treated as such. Small base dies, possibly, but full length resizing ALWAYS. Use chamber gages on the completed ammo, and use them or a bump gage to set your dies for resizing. Not the same thing as loading for a bolt gun, but not really difficult, either.
