I have a Kimber 8400 Montana in .325 WSM. I'm thinking of selling or trading to get one in .300 WSM. My thoughts are the ammo for .300 WSM will be less expensive and more easily found. I'm not a reloader and probably won't be in the near future and the cost of .325 ammo is killing me. Is my thinking off base? BTW, this rifle will see more use in the lower 48 than here.
