M80 vs M855 bullet drop for ACOG
I just acquired another ACOG, TA31RCO-m150(same as m4). It was intended for the Scar 16 but as its still wearing an Aimpoint Pro I put it on the 17 until range day. The pro was going to go on the 17 which got me started with this. Trying to figure out if the .308 has a similar way to zero as the .223, how we do the 50/200. Anyway, sitting on the 17 its looking very nice. I also already have a 14.5” ar with an RCO.
Hoping others with more experience can correct or advise on what I have here. Thanks
I used an app and input the following:
M855:
62 gr
BC: .283
Muzzle velocity: 2970
Sight height: 3”
M80:
147 gr
BC: .393
Muzzle velocity: 2750
Sight height: 3”
I did with a 100yd zero as well as 200.
