Re: .260 For Long Range Hunting?
I shoot a 6.5-08 aka .260 Rem in my XTC match rifle. Shoots pretty well when the driver is up to it. I haven't used it for hunting yet (haven't done much of *any* hunting for a while [img]images/icons/frown.gif[/img] ), but IIRC the 'standard' numbers I recall people giving as minimums for retained energy were 1000ft-lbs for an elk, or 800ft-lbs for a deer. The load I'm shooting now (for the moment) propels a 142gr SMK (moly) @ 2815fps from a 30" barrel (got up to 2940, but things were a little sticky, w/o much benefit in the wind for the extra wear and tear... one or two clicks on a 1/4 MOA sight), and according to RSI Shooting Lab it has the following retained energy levels:
Accuracy was about 1/2 MOA @ 300yds, scored a 95-1X @ 900yds (iron sights) when the driver momentarily got his stuff all in one sock [img]images/icons/grin.gif[/img]
From what I recall running the numbers for a .308 and for the .260, as a general rule (general is the key word here) since the .260 starts out slightly faster w/ a higher B.C. bullet (in general) than a .308 Winchester, it should be good to go in terms of ft-lbs at any distance a .308 Winchester would be acceptable. Now whether or not you would rather have a bigger frontal area, raw mass impacting the target, whatever, I can't argue one way or the other.
