In the light of this, Elbonia is reopening its decision for 6.8x51.

Also, am I reading this correctly that the US are now l;iable to have 6.5x43. 6.5 Creedmoor and 6.8x51 for the same job? nevermind 5.56 and 7.62?

My understanding is the 6.5x43 LICC and 6.5 CM are being evaluated by Special Forces, primarily for COIN, LIC.

6.8x51 is being developed for the Army, with primary intended use against near peer foes in conventional HIC.

So no, not intended for the same job, although they all potentially could be, if appropriate ammo is developed.

I suspect an OTM copper will be a little closer to the weight of an EPR round than a solid copper, as the steel/copper hybrid of an EPR will be lighter then a copper solid. 

what are OTM and EPR bullets?

OTM is ‘open tip Match’. They are bullets with a little hole in the nose. While they appear to be Jacketed Hollow Points (JHP) they do not expand like JHP. Instead they fragment dramatically, similar to 5.56 FMJ, but do so at lower velocities. 
 

EPR stands for Enhanced Performance Round. This is the projectile used by the US in the M855A1 5.56 and M80A1 7.62. It’s a 3 piece bullet (copper base and jacket, hardened steel front nose). Hardened steel allows is to penetrate barriers and some Level III / III+ armor. The 3 piece design also allows the bullet to reliably fragment at low velocities (~1700fps tested, threshold unknown).

OTM = Open Tip Match.  It's a propaganda term originally used by the US JAG in justifying approval for combat use of M852 ammo, which is loaded with the Sierra 168gr MatchKing hollow point bullet.

Construction is nearly identical to the Sierra GameKing hollow point, differing only in size and configuration of the tip opening.  Some SMK lots with oversize openings reportedly expand like the SGK.

Prior to the Gulf War, the so-called "open tip match" bullets were considered unlawful for warfare.
