For precision, it's Lapua and Norma. I use a fair bit of LC for my ARs. It's mostly Winchester after that due to quality and availability. Next is Remington and finally Federal. Funny, I've always had exceptional accuracy using factory Federal ammo, but for reloading purposes, the brass is crap. I've got a bunch of Privi on hand for some milsurps, but haven't gotten around to annealing it yet. Oddman out is Starline. I picked up some for my. 45-70 Marlin last fall. With my own cast bullets the Starline has been performing very well. I'd definitely like to pick up some more to do additional testing in other calibers.
