And I think 6.5 Creed is practically perfect for any shade of Yak,but would defer to the judgement of Steve Tims,aka Dogzapper.
If I remember correctly,Steve and his lovely wife have slain Yak,and eaten such having cooked it afterwards .
My personal experience with Yak is far more limited,I once asked a Canadian guide where the Yak sleds were in his part of Canada. He told me they were scarce around Moose Jaw,and seemed offended that I even asked.
Which is the point anyway. You can't count on foreigners or Creedmoor bashers to think rationally about anything.
