What I am wanting to know is can you design and manufacture an air rifle barrel to suit a certain diameter projectile. Various reasons why I’d like to do it this way. Availability of slugs is an issue where I’m located. The caliber is .25. The slug diameter is .2505. I want to get a barrel...
Has anyone tried the new FX .25 heavy or slug liner they seem to be 1:16 twist rate now. There were problems with the 1:18 twist rate and now FX have come out with this new one. Are we the consumer doing the R&D for FX?? photos taken from FB.
