terbzz...check some ballistic tables bud! all 3 calibers are practically equal...very small diffrences..accuracy?? HA...im almost posative the well known marine sniper Carlos Hathcock used a model 70 in 3006. and the 308 is a heavily used caliber by many snipers and sharpshooters!!

that being said with the right bullet and the right shot your tracking job will be short or there wont be a tracking job. ive dropped deer in their tracks with both calibers(308 and 3006) out to 150yds. never had a tracking job..either drop or watch em drop...
