My personal choice of weapons or hypothetical deployment scenarios isn't the topic. I simply said post COHERENT and RATIONAL questions and responses.

I have had better luck accuracy-wise with 1/8 over 1/7, in my own limited personal experience.
Larue 1/8 twist barrels are incredibly accurate with everything.
So you are saying even though the path is an arc, the rifle bullet itself maintains the same pitch? I never knew that and I think it is interesting. I am going to have to pay closer attention at the shape of the bullet holes when it is my turn to pull targets.
Is the same true for handgun projectiles fired at distance, say 100-200 yards?
The fastest twist .223 barrel I own is 1:8 and it does well from 100 to 600 yards with 52g-80g projectiles. If I decide to try shooting 1000 yards with a .223, it will require shooting heavier projectiles and I will have to go to a faster twist.
[QUOTE=Todd.K;1862192}the bullet not tracking the trajectory theroy has never been observed in rifle trajectories that I know of. It comes from artillery or mortars where the projectile has to make a VERY sharp turn at the top of a VERY steep trajectory.[/QUOTE]

In particular: At this extreme surveyed range, the angle of fall of the Martini 480-grain lead bullets was about 65 degrees to 70 degrees judging from the holes in the moist sand. Bullets were found in the sand behind the 22-foot-high target at a distance of only 35 feet. It was evident that they struck the sand point on, as the lead noses were always found rough.
...and
In this respect the Armory's 500-grain balls surpassed the Martini's 480-grain balls, which did not penetrate more than 6 inches into sand. In trying to get the correct 3,200-yard elevation, the long range bullets were thrown over 300 yards beyond the target. These were then dug out of the beach and all were found to have struck point on
Rifle bullets do nose over & follow the path of trajectory
Though I'm not a big fan, Todd Hodnettt covers it on the magpul video.

I've been searching that site and haven't found anything definitive. Someone got a link? So far, all I've found is that in the case of the Sandy Hook Long Range tests, bullets do indeed nose over to follow the trajectory
As I understand it we wouldn't have spin drift if the bullet wasn't trying to follow the trajectory
