Just looked at the specs....ain't that a 260?
Exactly.
And the 6.5x55 is a bit more than that.
And the 6.5-06 a bit more than that.
And the .264 Win Mag a bit more than that.
I like the high SD of 140 grain, 6.5mm bullets for ballistics purposes, but at 400 yard and closer hunting ranges, a 100 grain spitzer in a .257 Roberts kills deer just as dead, just as easily.
