Pre safey 336 with micro groove rifling. Hodgdon website for the load, although not specifically for the FTX. I didn't realize until after loading a few up that the FTX may require a different load than other 200 grain bullets. Bullet seated to the crimp ring and crimped. I'll get a chrono and see how they're doin' velocity wise. For this application (short range in brush) 1600+ fps should be fine.
