I have shot 2 coyotes with the 210g VLD out of a 300 RUM. Muzzle velocity is 3000fps. They have not been long shots by any means, 120, and 275, but boy do they leave some nasty exits. Both coyotes, you could stick both fists through them and still have some room. I would like to use them on deer this year. I think they work amazingly well. Of course your muzzle velocity is going to be a lot slower, so maybe expansion might not be as violent coming from a .308. I have hit my steel gong at 1150 with the 210g VLD's and they leave a dimple about 1/4" deep, and theres a decent bulge on the other side. They smack it with some authority when it gets there as well. I wouldn't use them on anything tough like a bear or elk.
