Hi!
Please post ballistics of the 5.45 ammo.
I just got my 5.45 rifle and I bought Kalinka Optics 4x 400m range finding scope for it with BDC for 7.62 I think. So I wonder how it compares to 5.45.

Thanks!

Here's a link with some basic info: http://www.militaryf...stics-chart.asp

This is from 1982 Russian AK-74 military manual for
53 grain military round from a 16.3 inch barrel with a muzzle velocity of 2970 ft/sec
(Which should line up perfectly for the saiga using Russian military surplus)

if you want I have data for longer ranges… let me know

Velocity in ft/sec
Distance in meters
0 = 2970
100 = 2673
200 = 2340
300 = 2056
400 = 1792
500 = 1508
600 = 1310

Wind Drift for 10mph at 90 deg.
100 = 1.2in
200 = 4.3in
300 = 9.1in
400 = 20.5in
500 = 34.3in
600 = 52.8in

Bullet drop in inches
Zero at 100 meters (sight set at 1)
50m = 0
100m = 0

Zero at 200 meters (sight set at 2)
50m = 1.2
100m = 2
150m = 2
200m = 0
250m = -3.9
300m = -9.8

Zero at 300 meters (sight set at 3)
50m = 2.4
100m = 5.1
150m = 6.7
200m = 6.3
250m = 4.3
300m = 0
350m = -6.7
400m = -16.9

Zero at 400 meters (sight set at 4)
50m = 4.3
100m = 9.4
150m = 13
200m = 15
250m = 14.6

Now this is what I am talking about. Great Post!!! Something that everyone can use, no matter what 5.45 you end up with.

how does that compare to the 556?

Thanks for that info, it is extremely useful.

Or you could just get a chronograph and get the ballistics yourself...

Do you know the Ballistic coefficient of 7n6? Without it the chrono data is not so useful.

Why is the Chronograph data not so good? its a long process, but wait a few minutes for the barrel to cool in between shots, for accurate and consistent data. Far as the BC of the 7n6, im not sure, you may want to ask Nalioth or Azrial or someone like them...

What about the 60 grain bullets? the 60 gr are the current military round
