As of now, the .44 cartridges are used by one revolver (.44 Wildcat and Panther magnums) and one lever action rifle (Moradi Model 1894). It would be fun to see a way to unlock the .44 nose hard cartriges without needing to use handguns, since in this case, it is used by more than 1 type of firearm. I dont enjoy hunting with handguns (in general), so having to grind countless hunts with handguns only to unlock a .44 for my rifle seems unatural.
I believe that this is the case with other firearms, but I am not sure on that.
Thats it, thank you!
