My brother occasionally uses a 270 with 90-gr hollowpoints to hunt prairie dogs. The trick is to keep the m.v. under 3,000 fps. Now that I have a 270 wsm, I'm curious to see what loads will work on the critters. I guess I'm just Scottish enough to want a gun that I can hunt elk or prairie dogs with. I've got a great benchrest 22-250 that'll do the trick, as well as a bunch of rimfires, but I just like testing the limits of a gun's versatility.
