With Titegroup, you have to hesitate a half second on the bottom of the stroke so the little tiny orifice can fill.
Learned that last year, no more short powder drops. Push the handle down, hold for a second, pull it up.
Just a little technique. In fact, I do that with all loads now, and I feel it gives me better control of the powder charge.
After all, it's not a speed contest. My aim is to make the best load possible for a reasonable cost.
