Flatter trajectory very similar to 6.5 Creedmoor, lower recoil.
You can get the same felt recoil with a Grendel if you shoot 107gr SMK/TMK compared to the 105-108gr 6mm bullets, but the 6mm 105gr+ class of bullets have much higher BCs.
6mm 108gr ELD-M is .536 G1 BC/.270 G7
6.5mm 107gr TMK is .445 G1
6.5mm 107gr SMK is .406-.420 G1
You get higher hit probability and better sight picture stability during the shot when shooting the lighter weights with higher BCs.
Cartridge stack in the magazine is easier for the spring to lift with lighter weight bullets as well, and easier to carry loaded mags for the soldier.
