The best hunting bullets in 6,5mm is:
For normal range 0-200 meters, and game up to moose size:
Lapua 155gr Mega, Norma 156gr Oryx, Rhino 140 and 150gr, North Fork 140gr, swift a-frame 140gr. Barnes 130gr TSX. These bullets have exeptionally good terminal performance, especially the 10,1 gram bullets is meatsavers.
For normal - medium range 0-400 meters
Nosler accubond, swift scirocco, hornady interbond, barnes 127lrx. Good terminal performance, and decent BC.
For long range 200-800 meters.
Hornady ELD-M 140 and 147gr, berger 140 and 156gr, Sierra, nosler ablr 142 ++
Poor terminal performance, but good bc and they expand at low velocity.
