[QUOTE="Greyfox, post: 670212, member: 10291"] I have done a lot of testing with two 6,5x284 rifle using both new and fire formed Lapua brass. I see no difference in velocity between the two with my Cooper, I do see a velocity difference with my Savage, about 30 FPS faster with FL resize. I always FL resize for feeding reliability purposes. The important aspect with new brass is to make sure the neck diameter is the same as your fire formed dye set up. Also chamfer and check length. With new brass I usually have to expand the neck to match tension, even though I don't always use a neck expander for my fire formed reloads. Having said all that, I prefer to always use fire formed reloads for critical ballistic testing and LR hunting. I will use new brass for trying different bullets, powders, primers etc.at shorter ranges, check results, and if I want to pursue the new parameter, I will confirm with fire formed brass. [/QUOTE]
