First, the Federal brass: I use quite a lot of Federal 308 Brass but only for shot to mid-range loads where I don't have to push it too hard. Primer pockets will loosen a bitg earlier than in Lapua or Winchester brass. I like around 43 grains of 4895 with 155's out to 600m. For 7,8, and 900, I use Lapua brass and add a couple grains of powder. I have always gotten better accuracy out of 4895 than Varget but have been able to get better velocities with Varget. Sometimes, a guy might want to go for the velocity to ensure stability at 1000 yds.
I also use some Lake city Match brass and it is strong and durable but capacity is a bit lower. My favorite bullets are the Lapua Scenars. GD
