Slidellkid: I have killed several Buck Antelope and one Deer with the 100 grain Nosler Ballistic Tips fired from my 260 Remington.
These bullets were VERY lethal on the aforementioned animals as all were one shot kills.
This is also an excellent fast and flat flying Coyote bullet - although it is NOT fur friendly.
Best of luck with your 260.
