I've had two 260s, one a Model 7 and the other a 26" M700VLS.  The M700 was by far the most accurate, but I never carried it far big game hunting - it is a fine long range varmint rifle though.  The M7 accounted for deer and caribou and was great to carry, but I sold the M7 and kept the M700.  The M700 has taken one Texas deer, the only one I fired it at, and a bunch of varmints.
