Re: which caliber for all around use?
NONE of the rounds you mention are worthy beyond 1000/1200 yards. The 308 would be the closest but a shot at 1500/2000 as you mention would simply be pure luck. A properly scoped 300 Wini Mag is probably the minimum caliber that may be effective at those ranges. I' opt for a properly scoped .338 Lapua Magnum or 8.6x70 which is designed for shots out to 2000 + yards. With a proper scope your talking around $3000
