looking at the guns you already have,if i had to, i would get the .300 wsm just because the 7mm and 30-06 have pretty close ballistics. You live in kansas so whitetail, i dont think there are bear there? maybe mule deer? i wouldn't buy either. Use your 7mm. that caliber has enough power and range for almost anything in north america. I'd keep the money and by something unique, caliber or cosmetically.
