6.5 Grendel on it's own merits

[Stinky Coyote]

Yeah you have to define what you shoot before saying one is better than other. Paper/steel punchers at distance go 6mm, impact velocities offer 150-170 yard advantage over Grendel (103/8 vs 123 eld-m) for hunting but problem is most hunting is sub 500 yard game and most ar length cartridge hunting is under than and the Grendel has plenty of impact velocity within that so will take the bigger pill all day, the added 'range' of the Arc is useless in hunting unless you're of the very few who would do extra long range hunting and especially so with an AR length cartridge. And short barrel length efficiencies to the slower of the two also would be my take. Unless you’re into competition or extreme long distance shooting/hunting the Grendel hits more check boxes, is more rounded and versatile without being weak anywhere. The 6.5 Creedmoor will always get the nod over the 6mm Creedmoor, its an age old thing, 260 vs .243, the 6mm vs 6.5 but the formula is no different for these shorties but hunting the 6.5 always gets the nod over the 6mm options. Target work seems to favour the 6mm's.
