When someone mentions the 7.62×39 Russian cartridge, accurate isn’t usually a word that comes to mind.
The cartridge itself is capable of decent accuracy, the problem lies with the type of firearms usually chambered for the cartridge are not usually designed to be tack drivers.
We are all familiar with the SKS and AK rifles that are rugged and reliable, but we feel lucky when we can hold a 3 inch group at 100 yards.
Around ten years ago, I bought a CZ527M chambered in 7.62×39, just to see how accurate the little round can be.
I played with it some and the little carbine usually averaged around 1.5” groups at 100 yards.
A couple of weeks ago I decided to actually attempt to tune a load for my little CZ, and see what it was capable of.
I ended up settling on a load using a Sierra 125 grain Pro-Hunter #2305 and 24.5 grains of Accurate 1680.*
This past weekend I shot three groups at 100 yards, all were 5 shot groups using sandbags for a rest. The results are as follows:
The three group average was .967”, not too bad for a factory carbine.
*While this load was safe in this rifle, it may not be safe in all firearms.
