777 powder FF vs FFF question
Just bought a new Omega and will go to the range next Monday. I have Pirodex pellets, but want to try loose powder. Nobody within 70 miles of me did not have 777 FFG in stock so I bought FFFG. I do not have experience with shooting loose powder. Is there something to know about measuring or amount of load of FF vs. FFF. I know that FFF is finer powder. Any input will be appreciated.
