A drop tube is a must for creating the best black powder cartridges. Trickling powder into your brass cartridge through the brass drop tube means that more powder can be used, and the powder settles helping it to burn cleaner and with more consistency, reduces fouling and improves accuracy.

This drop tube is made of oak and measures 24". Adjustable for various size cartridges. The copper tube is 3/8" in diameter. The base is 5-1/2" square.
