I have a .260 that I have used for several years with the 100 grain Sierra Varmint at about 3270 fps. This is a dandy round when a little wind comes up in South Dakota (Try 18mph for a start.) My experience tells me that this combination runs out of gas at about 700 yards.
I am further experimenting with the 7mm WSM.
That thing will put out a Burger 180 VLD (BC=.698) at about 2850 fps. My ballistics calculator tells me that I can get to 1000 yards with a come up of about 25 moa. (Sierra is about to launch a 175 SMK for this caliber as well.)
The rifle will also extrude a 100gr Sierra Varmint HP at a little over 3500, but I'm told a steady diet of these is not advisable. I will probably take 20 or so to the next hunt in case things need to be livened up a little. [img]images/icons/grin.gif[/img]
