I went through this about 10-11 years ago, and after looking at everything that was available- I went with a .270 Weatherby. I don’t think it was the wrong choice, either. Then again- neither would a .264 Winchester, or a 7mm Remington Magnum, or a .300 Winchester. Depends on if you want to be able to buy ammo off the shelf, or if you like to hand load- then again, the brass for Weatherby’s is more expensive, so either way you could take that into consideration, but in the grand scheme of things, I feel like that is inconsequential.
What everyone above said is true- pretty much anything will work, but I think I know where your head is at- you want something that is the best tool for the job at hand. Get a fast, flat shooting cartridge and learn where it shoots and the system you decide to use with it (adjustable turrets, BDC reticles, or KY windage), and you’ll be just fine. Just don’t buy a 6.5 CM- that would be silly.
