What seems to be the common issues with the m10x? other than the dismal accuracy?
With the M10X I'd say it is:
#1: Cost.
#2: weight.
#3: let down in the features for the cost, with accuracy being the most noticeable.
As has been beaten to death, no one is expecting great accuracy from surplus ammo, and certainly not surplus 7.62x39.
The question then turns to, 'what about other ammo other than surplus?'
Not everyone wants to burn surplus ammo, or at least surplus ammo alone - and despite it's poor reputation for being an 'inaccurate' round, 7.62x39 can offer very good accuracy.
It's a good short range game cartridge, and a good all-round blaster. Light on the shoulder with just enough oomph for that dear in the fall - what's not to love?
For the price, this thing should burn through the surplus while offering up so-so accuracy, and then perform better than average with quality ammo without batting an eye.
Thing is, it's doing a mediocre job at all of it.
Want a plinker to shoot fodder? You could get a T-81
Want a decent rifle you can hunt with and shoot decent x39 well? You could get a CZ-527
Hell, get both a T-81 and a CZ-527 for less than one of these...
