Which one is more accurate?

 

[skyugo]

you can find better ammo for .223.

i'd say for a battle rifle or even a designated marksman type rifle, either will do the job though.

5.45 is generally regarded as more reliable than .223 in AK's.

I shoot my polish tantal 5.45 all the time. My dad's norinco .223 just sits in his closet. He says "ammo's too expensive". Take that for what it's worth.

iron sights bulgy 5.45 vs sar 3
bulgy by about 1.5" at 200 yards iron tested last week.

Bulgy 545 at 500 yards iron sights vs 14.5 bushy iron sights in a heavy variable cross wind (over 18" drift on the bushy)

target was 18" high by 36 long.
Bulgy 5 hits out of 30
Bushy 15 out of 30

this may be because the wind probably pushed the 5.45 more

Depends on the rifle more than the caliber of the ammo. All things being equal I would say the 5.56.

Alright, I am a bit of a noob when it comes to the 5.45, though I did used to have a Bulgarian SLR 105R (banned model) that I took on trade back when 5.45 was insanely expensive. I later traded it before shooting it, and shortly thereafter ammo came way down for it.

SO, again, how does the 7.62x39 factor into this comaprison?

He can give it to me I'll put it to good use

762 can be accurate but it has a rainbow like trajectory
