I've decided to leave it as it is for now and alter my HW80 insted. I'm after .25 for that bit more stopping power for short distance rats, only about 15 yards max. I'll keep the HW zeroed at close range and the rapid can stay as it is around the 30 yard mark. If your after a place to get a .177/.20/.22 barrel for your rapid try the link below, they're about £90 depending on what length you want
