The 257 WBY is a great caliber. /ubbthreads/images/graemlins/grinning-smiley-003.gif I own one and so do my step dad, uncle, and four other friends. In fact it is my favorite caliber. I love studying ballistics and it doesn't get much better w/o going to some custom made job. Everyone I've ever seen or shot shoots incredible. I haven't found a factory offering that won't shoot 1 MOA from either my step dad's or my gun. My step dad and I started off using it as an all around gun, but it is definitely over kill for predators and varmints. Based on the threads here, I decided to add an AR-15 (223) to my arsenal and couldn't be happier. /ubbthreads/images/graemlins/grin.gif The 257 is now my deer/antelope gun. I think you should get the 257. Start off by using it for deer and coyotes, but don't be surprised if you end up buying a more "traditional" varmint caliber in the future. Just like someone said above, if you end up shooting it a lot, you'll get sick of spending over $40 per box of ammo to shoot coyotes. There is also little chance of actually seeing the impact of the shot through your scope with a magnum. Heavy barreled 223’s and 204’s are pretty nice for that, especially if you take it prairie dog hunting.
