FPS Data for BCM 18" Upper? Certain Ammo I need Info for.

Hey guys!

I'm trying to turn my BCM AR with an 18" SS upper into an SPR project. I'd like to take it as far out as it can go, realistically about 800 yards, but for learning and target purposes, 1000 yards.

I bought the Vortex 2.5-10x32 FFP HS LR optic, an MOA optic with windage tick marks:

The upper I'm using is one from BCM:

Due to variations between rifle designs and the long ranges I'm trying to work with, I'm trying to get exact, or close, bullet fps speeds for the following bullets:

M193 55 grain
M855 62 grain
Black Hills 69 Grain OTM SMK
Black Hills 69 Grain TMK SMK
Black Hills 77 Grain OTM SMK
Black Hills 77 Grain TMK SMK

Does anyone have any of this info out of this rifle? I have a 100 yard indoor shooting range and I won't be able to pick up a chrony for a bit. I can guesstimate, but if anyone has data that'd be awesome!
