What level of performance are you wanting? I believe the Jazz (7mm-300 Norma Imp) will push the 180 Berger faster (and 195 Berger, if it ever gets produced), but it's over kill if you want to easily push the 180 to 3050-3100 fps. The Jazz will be much more brass prep, but the Norma brass could last a lot longer. 28 Nosler brass can be made from RUM brass with the right dies. The Jazz requires a larger bolt face than the Nosler.
