I attended the National Matches at Camp Perry in the late 70’s as an Army Reserve volunteer.^ That chart is pretty darn close. With a .308 (atmospherics depending...i.e. elevation, pressure, temp) you are in the 390-410" of drop at 1K yards with a 175gr SMK.
When I used to compete in service rifle matches I had the opportunity to go to Quantico and shoot on their Range 4 several times. All service members were required to use either a .308 or 5.56...and the vast majority used 5.56 with Iron sights, and the 80gr SMK at the 1K yard line.
Seeing the bullet trace start out 20' into the trees that were on top of the berm...disappear at about the 500 yard mark as it was just coming down...and then seeing the target go down and come back up with a hit in the 10 ring was pretty impressive. You're talking in the neighborhood of 33 feet of drop.
One day we had to shoot in a 20+MPH full value crosswind. I think we were shooting 140ish inches of wind drift. The bullet was literally starting at the far edge of the 6' target NEXT to yours and drifting back in. 33 feet of drop...12 feet of drift.
I worked the night shift so I could watch the 1000 yard matches. At that time the 30-06 was still very much in use by many of the contestants.
I was amazed at the wind flags showing direction were pointed in many different directions and how they could read the winds to get a bullet on target at that range.
Now LR shooters are looking at 2 mile shots.
I read a story awhile back about how much elevation is required to make that shot and it was incredible. Bullet flight time was a tad under 3 seconds.
