Damn! What's the barrel life, one mag dump?

FN knows how to build barrels, I'd bet it is within accepted parameters.

I don't understand the rationale for 6.5 CM in a machine gun. It can't be accuracy/precision or extension of range. I would think the 7.62 would be more robust against barriers. Of course it is marketed towards special forces, so it probably mission specific.

I would say "ammo commonality".

Surprised they went with 6.5 CM and not 260?

I thought the purpose of the 260 was better feeding in machine guns?

The 260 Remington was never developed with any military use in mind. I would think that FN engineers know better than all of us what feeds well through their gun and what not.

No doubt.

Perhaps I mis-remember but I seem to recall seeing somewhere in a 260 vs 6.5 CM discussion that the 260 was "friendlier" to automatic fire. Perhaps I got it backwards.

My bet is that whomever said that is speculating based on the fact that the 260 is nothing more than a 308 Winchester necked to .264.

Commonality with who?
