I saw an FN FAL (Wiki)at the Aldershot military show in England and they allowed civilians to fire it using a 22 sub caliber adapter.  It took many years to find that H&K made the adapter and get one.

The rifle markings: ".308 Match", "Fabrique Nationale D'Armes De Guerre-Herstal-Belgique", "Browning Arms Co, Morgan, Utah".
The scope markings: "Hensoldt Wetzlar" (Wiki: Carl Zeiss)), "12-120-9556", "BMVtdg 30", "Made in Germany"
Bayonet markings: "Solingen, Germany"
22 Adapter markings: Box: "Einsteckgert 5,6mm x 16 fur Gewehr G1, -Ausfuhrng B-" (note this lable is not correct, i.e. the box was for an M16 sub calibre device)
                                         " Conversion Kit 7.62 Millimeter Rifle .22 Inch Calibre L12A1 (for the L12A1 FAL or similar rifle)
                                         "6920-12-147-6954" (NSN)
                                          made by H&K

This is really a seperate topic, but for now I'll park it here.
When shooting at a range of 1,000 yards (about the same as 1,000 meters) there are a number of corrections to the aiming point that need to be made.
Wiki has a section titled "Long Range Factors" on their External Balistics web page.  Wiki also has web pages for:
I've ordered the book "New Exact Small Arms Ballistics: The Source Book for Riflemen" by Arthur J. Pejsa
It turns out that the Coriolis Effect (Wiki) is very important at 1000 yards (more important than some of the more commen ideas).
The Eötvös effect (Wiki) may also be important (don't remember it being in the book).  Both of these are because the Earth is rotating.

Pejsa points out that the stability of a projectile is improved if the center of gravity (Cg) is at the same location as the center of pressure (Cp).  When these are at different locations the projectile is less stable.  Is there a commercial .308 round where these are at the same location?  Let me know.

The Mk44 Bushmaster II (Wiki, Alliant Techsystems) is demonstrated on Future Weapons Season 3 (NetFlix streaming video).  The interesting thing is that after using a laser range finder to determine the distance to the target then programming the shell to explode either just prior to the target, at the target or after going some distance behind the target.  This is similar to the capability of the 25mm grenade rounds that are being developed.  The Mk44 does this by measuring the Earth's magnetic filed and using that to count the rotation of the round.  Patent 5497704 Multifunctional magnetic fuse explains how it works.  Note the fuse includes an impact sensor, time delay, turn counting, magnetic (proximity) sensor .  After the programmed number of turns the shell explodes.  The muzzle velocity is about 1,000 meters/second so for 1 meter stability the rifling pitch is about 1 turn per meter.

The CheyTac Intervention (Wiki, ) fires the .408 Chey Tac (Wiki) round which includes the patented (patent 6629669) Balanced-flight / controlled-spin projectile concept.  The outline of the .408 is very similar to the Barrett .416 (Wiki) (I wonder if Barrett copied the .408 but made it a little different?).  The Barrett Optical Ranging System (BORS) is based on the old fashioned BC idea and includes left-right tilt which Pejsa has shown to be a fealty idea.

Accuracy International (Wiki) makes sniper rifles in various calibers but not the .408 or .416.
