Silver State Ammo 223/556 64 grain Nosler Bonded Solid Base

[andrewctillman]

Has anyone chronographed this ammo from either a 16 or 20 inch barrel?

Box states 2820 fps.

I think that is similar to Ranger 556B which uses the same bullet, from a 16 inch.

Ranger makes about 2950 fps from a 20 inch.

If anyone knows if the SSA is loaded to SAMMI or NATO pressure I would love to know.

Good deal on this ammo from several sources.

while not exactly the same, I did chrono a box of Nosler Custom Defense load with 64 gr NBSB bullet. It chrono'd 2667 fps from a 20" barrel, 1 in 12 twist. It also appeared stable at 100 yards with no indication of yawing or tumbling due to lack of stabilization.
