The increase in popularity of sub 22 Caliber reloading continues to grow and Redding responds to market demands by adding a new Lexan drop tube adapter for use with 17 and 20 caliber cartridges. The adapter is a simple friction fit and works with all Redding powder measures and the Redding powder funnel. Not simply a reducer, this adapter is manufactured with an integral chamber, engineered and tested to provide smooth powder flow and reduced bridging as the powder flows through the smaller orifice for the 17 and 20 caliber case necks.
