Good results, analytical description of your hunt, good information, good post. Most guides have little interest in the shooting sports, it sounds like you knew how to address his limitations on this respectfully. I am surprised just how the bullet performed, in our country, the west slope of the Canadian Rockies the country is steep and timbered, lots of avalanche chutes. I like a blood trail( depending on the chambering) but I would likely not use a bullet that would get through the shoulder and ( hopefully)exit. I have seen them well hit and die in the dirtiest tangles, also In hunting camp seldom would you see two guides agree on this or much else. I am speaking from experience, some of the laziest people I have every worked around were hunting guides and alternatively some of the most motivated. Any mature bull is a good bull. Cheers.
