Ya, to me though I don't care if he shot it at 1 yd, used a drill bit or a sharpie. The information contained about drop is accurate and the reasons to pick a zero are good.
No they aren't. That video is all sorts of fucked up.
I don't know shit about combat, but any schmuck like myself with a ballistic computer, an accurate rifle, a rangefinder and time behind the gun can calculate external ballistics.
Assuming M855, 62gr, .304 bc, 2900fps, 2.6" height above bore:
-----------------------------------------------------------------------------
25 yd zero
50 yd +2.3"
75yd +4.3"
100yd +6"
200yd +9.4"
300yd +6.2"
400yd -5.2"
Shown: 50 and 75yd impacts almost on top of each other
-----------------------------------------------------------------------------
50yd zero
No discrepancy in data shown. See the 200yd zero below.
-----------------------------------------------------------------------------
100yd zero
25yd -1.5"
50yd -0.7"
75yd -0.2"
100yd 0
200yd -2.6"
300yd -11.7"
Shown: 25 and 50yd "impacts" ~3" above the POA. With a 100 yard zero there are never impacts above your dot.
300yd "impact" is shown ~3" above a previously quoted -24" impact from the 25yd target. It should be half of that.
-----------------------------------------------------------------------------
200yd zero
25yd -1.2"
50yd -0.1" (Almost zero)
100yd +1.3"
200yd 0
300yd -7.8"
Shown: 25yd "impact" right next to the 50 and 200 "impacts." He speaks like the 200 yard zero is different/better than a 50 yard zero, when they are almost identical, and he has the 50/200 impacts right next to each other.
-----------------------------------------------------------------------------
300yd zero
25yd -0.5"
50yd +1.2"
75yd +2.7"
100yd +3.9"
200yd +5.2"
300yd 0
Shown: 25yd "impact" ~1.5" above POA.
-----------------------------------------------------------------------------
His math is off and he didn't shoot it at the stated distances. There is nothing credible about this video.
