My Browning A-Bolt 30-06 with the Boss shoots the 165 Nosler Partition as good as any Sierra Bullet i have tried in it.
Bea mostly, yes. With the 06 I noticed a tendency for the Sierra 165 to shoot slightly better than the 165 NPT but it showed up at the 500 yard line and over a few groups....even then, it was not enough to matter on any BG animal.
