Rifle Scopes What ammo is the EOTech 557 calibrated to?

[planalpha]

I was checking to see what ammo the EOTech 557 BDC is calibrated to. Their site says "Ballistic reticle specific to .223 caliber munitions" which is not exactly helpful. It's on a S&W M&P 15T with a 16in barrel if that helps. Anyone test it out. I'm guessing m855.

Thanks

Do you know by chance of the 553 is calibrated to the same?

557 4 dot is calibrated for M885 (62 gr. FMJ 2,680 FPS from a 14'' barrel).
553 will be about the same, but its a .223 62 gr. at 2900 FPS.
