[QUOTE="landcbeitner, post: 187766, member: 10214"] Sounds like you'll have a very capable long range set up there. From what I've experienced seperating the cases by weight makes a bigger difference for accuracy than using a high end brand of brass. I use Lapua and Norma brass, but I've shot just as well when using seperated winchester. I spend quite a bit of time on brass prep, I always inspect thuroughly, trim, uniform flash-holes, sort by weight, deburr the neck etc. I haven't messed with the neck-turning yet (although my buddy has a neck turner) because I'm satisfied with my accuracy. If you wanted to neck turn, I'd recomend having your chamber cut with a tight-neck. Bullet seating is something you must test. Some bullets like Sierra, Nosler, and Hornady are "jump tollerant" I usually seat these around .020" off the lands, but you can usually jump further without accuracy loss. For Bergers and Scenars I usually end up a .010" or closer, they don't like to jump for me. I first develop the load (usually figured on Optimal Charge Weight theory) and then experiment with seating depth to get the best accuracy possible with a given combination. You may want to experiment with OCW loading. Here's a 10 shot group from two different loads (5 rounds each) one had 44.8gr Varget and the other was 45.1gr Varget behind a 155gr Lapua Scenar (308 win).
