Can't imagine that the 50/200 thing still holds true.
I don't have a chrono so....
I'd like to chrono one as well.
This is just from info I've found about 5.45x39.
I don't know if this info is accurate or not.
Velocity = 2936fps, BC = 0.366 for a 60gr .214" boattail, optic of bore=2.75"
With a ballistics calculator this gives:
0yds = -2.75"
25yds = -1.24"
50yds = 0.00"
75yds = +.97"
100yds = +1.64"
125yds = +2.00"
150yds = +2.06"
175yds = +1.77"
200yds = +1.14"
225yds = +0.13"
250yds = -1.26"
275yds = -3.06"
300yds = -5.29"
Not as flat as an AR but not terrible either.
