Well...
Mine wasn't a CVA Kentucky, but is a "no-name" Spanish replica of a flintlock "tower pistol" and 30gr of FFFg was plenty strong in this one. It's not that I do MOT think 40 or 50g off FFFg of BP isn't a safe load or that the gun just isn't "good enough". I do NOT use Pyrodex or other substitute propellants, too hard to light, and 777 might just be a little too energetic for my use, BUT my load works just fine under tha circumstances.
ALWAYS use a BIG enough gun, AND shoot shafe/1
