I use 23.5 gr pf IMR3031 powder and slowly trickle it into the funnel giving it some swirling action.It's a little tedious but not that hard to do.I don't leave lube on the inside of the case mouth.Holding the bullet in line with the case mouth during bullet seating is a bit tedious too.Shawn do you use a progressive loader?Not sure why it would be so hard to get powder in the case otherwise.
