.223 russian ammo question

[stitchnicklas]

if it says steel case and polymer what does that mean???
is the polymer a lacquer ??
i find my ar15 does not like wolf ammo that much and i can get cases of this Russian ammo from centerfire systems for 124.00

any input???

The Wolff polymer coated stuff runs just fine in any AR I have. It's not that accurate but functions perfectly.

Polymer is not really a lacquer but more like a plastic. The only issues I know of with this stuff are leaving a round in a hot chamber and then letting it cool can cause the polymer to melt, then harden and make the case hard to extract when you fire or eject that round

My BCM has no problem with Wolf ammo
