Wind Drift for 10mph at 90 deg.

500 = 34.3in
600 = 52.8in

Bullet drop in inches
Zero at 100 meters (sight set at 1)
50m = 0
100m = 0
150m = -1.2
200m = -3.9

Zero at 200 meters (sight set at 2)
50m = 1.2
100m = 2

I like this post!

What are the main differences from 5.45 x 39 and:
7.62 x 39
and
5.56 x 45

If I were to get a Russian rifle for HD and Range, you recommend 5.45 x 39?

If could make a wild guess based on a hunch...
It seems like Russia had found that their forces might be out-ranged by the 5.56 x 45 cartridge and went with a smaller lighter weight round for their AK 74 model (faster and flatter).

I would be interested in seeing ft lbs. of all 3 at 100 - 400 yards.

Realistically none of them are good for home defense as they will all pass threw a grown man at close range, as well as most walls.

Buck shot from a 12g would be the best bet for home defense.

Deer and hog, 7.62x39 is great, 5.56 or 5.45, I only use on fox, coons, rabbits, and other small critters.

Not saying that u couldn't use 5.56 or 5.45 on large game, shot placement is key

As stated, 5.45 is not a HD round. It is an effective varmint round and works well on coyotes, using appropriate ammo.

Nice write up, Nathan!

One thing to consider, the really cheap surplus 5.45x39 is corrosive thus not a great choice for a direct impingment system. Also, AR magazines that reliably feed a full 30 5.45x39 rounds are rare and expensive - so what seems to be an initial advantage over 5.56x45 can shrink fast.

For most of us it's best to use 5.45x39 (and 7.62x39) in AKs and 5.56/.223 in ARs. Especially while cheap surplus stuff and cheap AKs are available.
