Hi guys. Time to play around with the 416 ruger I've had here for a couple years. Other than a little factory ammo, I've not done much with this gun. Curious what seems ot be the best powder for 350-400 grain pills. Also will be using speer 350s and a few different 400s. Other than the hornady book, reloading info seems hard to come by still. Any help would be greatly appreciated. Ryan
