According to Matt Dubber and others, the Avenger barrel is really good with slugs, great news! Trying to find specifics with the slugs but coming up short. Anyone with firsthand experience using either NSA .22 slugs or FX slugs in .22 and the Avenger? Interested in weight, size, velocity and gun settings. I'd prefer to test for myself but NSA is our of all the sample packs and FX is darn expensive to be buying a box of each.
