You may get away with a progressive loader, for F class. I don't think the powder measures is up to the task, I did some good loading on one for an AR. using 8208 and Harrells measure mount separate from the press to reduce the vibration. Now to use and load a sub .1 gun, it won't happen. BR. at 600 and 1000 is just to demanding 1/4 min.+ loading and i feel the same for F class if you want are on top of the game…….. you can't leave anything on the table…….. jim
