What is the 6.5 ammo weight? That was a huge issue with the M-14 if you wanted a decent amount with you.

6.5 Grendel

I measured 274.8 grains for a round with a 130gr bullet.

I measured 271.8 gr for a round with a 123 gr bullet.

I didn't have any 223 to compare it to.

The 6.5 G comes in at about 25 cartridges per pound. 5.56 x 45 M855 comes in at at about 50 per pound.
