My wife's 20" CTR .260 runs the 139 Scenar at 2725fps with 42.5gr IMR 4350. Our son killed a deer and an antelope with that bullet last year.
43.5 grains IMR4350 behind the 130 Accubonds clocked 2778 out of the same rifle today, she pounded steel/rocks out to 560... and didn't miss. She and the kids will be shooting that load at deer, elk, and antelope this fall.
