I use H&N FTT in all of my Weihrauchs now. I didn't have much luck with Air Arms in the Weihrauchs then started using the actual Weihrauch pellets. They proved to be the best which you would hope they would be really, but then they got expensive. It was then I read that the Weihrauch pellets were made by H&N used some of them to the accuracy of the Weihrauchs so then I was a convert to H&N in all my Weihrauch rifles. I use Air Airms in all my other rifles and was very happy when I only needed to buy 2 different types.
I then bought my first first and second PCP's and after pellet testing they preferred JSB's, so much for keeping the same pellets in all rifles.
