I took an antelope this season at 1285. My longest shot ever on a game animal. The set up before I decided to shoot took probably 15 minutes while I watched vegitation, mirage, and anything else I could to get for a reading if there was a wind. These were morning steller conditions. So I took the shot and the goat fell.
So lets look at your shot with the same rifle I used.
Dial up 26.7 MOA
30 mph full value (9:00) wind....... 15.7 MOA or about 15 1/2 FEET of drift
add 1 mph of wind to 31................16.2 moa or about 16 feet of drift
go to your max wind of 35 mph..... 18.2 Moa orabout 18 feet of drift
So the difference between 30 and 35 mph for this shot with my rifle and a High BC bullet would be 2 1/2 feet.
Couple that with the 1.52 seconds of flight time, the to of the bullet arc being 0ver 26 feet above line of sight and shooting across a canyon where the wind was surely stronger in the middle and a cold bore hit even close to the vitals would be more like a lottery win than marksmanship.
Even though we practice in similar conditions and have good equipment. Wind rules us all.
Good post!! You did the right thing! You deserve another chance at that bull and I hope you get it in better conditions and closer.
Short answer.......... Hell no I wouldn't touch that shot with a 10' pole. Unless it was a wolf...
