Did you have the bipod on the rifle when you zeroed? Did you verify your drops shooting off the bipod?
I am thinking the problem was not the shooting solution. One question on the solution though. If elevation/barometric pressure are not correct can cause a couple moa discrepancy.

Thanx, Steve. I did not have the bipod on when zeroing, but I did verify zero with the bipod. I "assumed" that if zero was the same with or without the bipod, then drops wouldn't be affected either. I'll correct that, I will definitely be verifying drops with a bipod. As for barometric pressure, the Geovid corrected for that - it read 22.8 in Hg, equivalent to about 7300' where I hunted.
In all cases
at the range, sighting in or practicing, with or without the bipod, the butt was supported with slight down pressure on the fore end. But when I shot at the bull, the butt was
not supported and there was no fore end down pressure. As several stated, this seems like the primary culprit. Pull trigger, bullet fires, gun kicks, butt drops, barrel tips up - and
then the bullet exits the muzzle. Sounds like it'll be high to me.
Other factors may have contributed, but supporting the butt end in prone position with a bipod will be the first corrections I'll field test.
