When you go to the range, be a scrounger! Look in the trash cans for the plastic trays that many company's use to hold the rounds in their boxes. These make wonderful loading trays. You can do batches of 50, or less, in stages. After the powder drop it is easy to compare the level in each case under good light. Set that tray full next to the press and on to the next step or load another tray! These trays fit US Army ammo cans very nicely for storage and/or transport. Use a piece of cardboard, cut to size, between each layer of trays.
