Pellet lube is the next thing to try as another shooter with the same rifle and the same issues has had good results.
However the Steyr problem seems unique to it. It's the only rifle I've ever shot which needs barrel attention. The Walther didn't really ever need anything, and nor has any other i've had. Not sure about AA EV2 & FTP as i've never owned one, and the s200 i had was in the days when I was just learning to shoot... that said I'd love it's barrel because that seemed tight without hassle.
I would pull the barrel and replace with a new Walther barrel simples
you will save time and money by fitting a good barrel
