Lets not get hung up on one video posted for entertainment.Like I said, that video showed a neck shot (even if the end didn't show the neck wound, the DRT is a clear spinal shot) - the wind drift was a lot more than 2 MOA. I shoot every day at LR in CO and several times per week when I am in AZ, and just that tree blowing told me it was more than 2 MOA.
I love my .308 but there are other cartridges that have less wind drift.
FWIW, I was the three-time undefeated US Army Alaska champ; shot twice in the I Corp (western US) championships and finished second and first. I didn't win those by failing to read the wind.
As for your drift claim, there is no way a 155 gr bullet drifts 4.5" at 600 yards - a Berger VLD at 2870 drifts 4.4 MOA - that is 26+ inches. My 28N launching 195 Bergers drifts 2.2 MOA.
As for your calcs on wind drift at 600 yards, you need to double check your figures. I am pushing those 155's at 3,000 fps in my 26" and according to my ballistic apps at my altitude, they are 4.5" and 4.75" at 600 yrds.
There is no way a 10 mph wind is blowing that load 26+ inches at 600. My apps show 25.6" at 1,000 yards
