Sorry but the chorny doesn't lie and it DOESN"T WORK for my inline. I think it was Semi or Sabot they found out too. Also I WASN'T using it as a cleaner. It consently produced lower fps even after wiping the bore out really really good. The first couple of shots are always lower and atleast 800 fps less then a clean dry barrel. The first shot was 1000 fps less! I just doesn't work for me. Now centerfires I don't know. But for my Triumph its a no.
