My mother got her 270 Magnum online at Dick’s Sporting Goods. My second choice caliber personally is just the 270 Magnum.
My all-time treasured would have to be the 243 Winchester and 270 Magnum. I got my Kimber in the hunting section at Gart Sports in Minerva, Nevada. One thing I don’t like is that adding a bullberry stock does increase the weight of the Kimber.
