The Raging Bull has never been offered in .444 Marlin. The Model 444 is chambered in .44 Rem Mag.
So, it's .44 Mag versus .454 Casull.
I had no idea. Wow! talk about someone not paying attention. I was looking at the 454 and read how it also chambered the 45 lc. I read the words raging bull 444 and just assumed. Well you know what they say about that word.
