After my range session on Friday, I discovered that my flintlock renegade prefers FFg for the main charge. My normal load of 100 grains FFg pushing a .430, 300 grain xtp prints 1" groups at 50 yards, but with FFFg the groups were like 5-6 inches at 50 yards. I tried 60-70-80 grain charges with the FFFg. Will stick with FFg for the main charge. Just a thought, if you know if likes FFg maybe stick with it. If it aint broke....
