So I'm thinking about building a 6.5 something. The rifle will be used mostly for shooting steel, but may see some use as my windy day coyote gun. I have done some research and I shoot with a couple guys that use 260's and a 6.5x47. Both calibers shoot well and bullets for a 6.5 seem to be readily available. The only down side to some of the 6.5's is velocity, it's a lot harder to dial wind at distance when your bullet starts out at 2700 fps. So this leads me to think about a .264wm or a 6.5x284. Whatever I do it will be geared around shooting the heavier end of 6.5 bullets. I don't need 4000fps, but I would like 3100fps. That's my story, I humbly ask for your knowledge and wisdom on this subject. Thanks
