The Area 419 Billet Powder Cup is lathe spun from billet 6061 Aluminum and weighs in at just over 700 grains; this cup has a water weight capacity of more than 750 grains and will allow you to throw nearly three full 50BMG loads into the cup at once. Of course you aren't going to triple-charge a 50 cal, but the over-sized cup will contain powder and splash from dispensers that are dropping powder from above, provided you use them with some sort of flow-slowing device (like the straws that come in the Auto-Throw kit). Nothing short of about a 5a ^2 cup can contain splash if you're dropping from above with no restriction. The Area 419 Cup is roughly 2a ^2 in diameter and 2a ^2 tall. The handle sticks out about 3a ^2.
