Before he buys a new rifle, he should consider the power still remaining at the 600 yard mark for that particular cartridge. Even a svelte 165 Accubond in the 308 drops 76" when sighted in at 200 yards; over 6 ft.....and energy falls down to the 1,000 ft/lbs or less. That's a pretty marginal Elk round at 600 yards.
