I've killed several mule deer and antelope with the 6.5 CM and 130 and 140 grain Accubonds. I've also seen a few more killed with the same loads. It seems like an ideal deer cartridge to me since it's accurate, low recoil and very effective. The 140's may be overkill for deer, but I really like the performance of the 130's and they shoot a little flatter with slightly less recoil.
