I would also go with the 180 gr. Barnes X load. I also recommend you start handloading ASAP. With quality handloading equipment (RCBS) you can probably load your first bullet for about $350.00. According to Cabelas catalogue your going to pay about $83.99 for a box (20 rounds) of .30-378 Wby. Mag. 180 gr. Barnes " X" Bullet. Four boxes of factory loads will cost you about $336.00. Good luck.
