Best tumbling commercial (non-corrosive) 5.45x39 round

[300grJHP]

Which non-corrosive ammo in 5.45x39 tumbles the best?  Does anyone have any experience?  I'm looking for something that tumbles as well as the surplus 7n9 ammo, but don't want it to be corrosive.  Does wolf or tula or barnaul silver bear tumble?

thanks,

I may be mistaken but I believe the 5.45x39 is a new enough cartridge that all will be non-corrosive.If you mean tumble after hitting your target.....they all will.
