Ammo for the TNW asr 9mm

[Prairiestorm]

Did some research didn't find anything really... Was just curious if anybody has had time to play around with ammo variety in TNW aero survival rifle in 9mm. Got one on order and headin to the gunshop in the next few days was wondering what I should be picking up ? 115gr or 124? Brands? more or less curious what people have had success and bad luck with

I've only tried 115gr Barnaul in my TNW so far, shoots it very accurately, like under 4" @100yrds. But my TNW does suffer from the occasional stove pipe. Which makes me wonder if it's not ejecting as strong as it should be, maybe shooting a higher gr will help with this, or maybe I screwed in the buffer tube too far when I replaced it.
