The RCBS UPM Drop Tube Sml (Part Number: 09023 / R09023) is a specialized, small-diameter replacement powder drop tube designed to route gunpowder from a manual powder measure directly into smaller-caliber cartridge cases. Molded from a specialized plastic formulation that resists static buildup, this component serves as a precise funneling channel to prevent powder loss and bridging during the reloading process.

Key Features

  • Static-Resistant Construction: Engineered from a specialized plastic formulation designed to minimize static cling, ensuring all powder charges flow smoothly without sticking to the interior walls.
  • Friction-Fit Integration: Press-fits directly into the bottom of the main casting of compatible powder measures, securing a tight seal that resists shifting or sliding out under mechanical vibration.
  • No-Spill Funneling: Features a tapered, narrow exit aperture that seats cleanly inside the neck of smaller cartridge cases to eliminate external powder leakage.
  • Factory Compatibility: Designed as a direct drop-in replacement part for the RCBS Uniflow Powder Measure (UPM), the RCBS Little Dandy Pistol Powder Measure, and the RCBS Du-O-Measure.

Who is the Rcbs Upm Drop Tube Sml for?

  • Handloaders reloading rifle calibres from .22 to 7mm — requires this lightweight 0.005 kg reloading powder drop tube to guide powder safely into cartridge necks between .22 and 7mm in diameter, ensuring a secure seal that prevents powder bridging or spilling over the case mouth.

Less suitable for: Handloaders loading larger cartridges measuring .30 calibre and larger, who require a wider large-diameter drop tube to prevent powder bridging, or those loading ultra-small sub-calibres from .17 to .20 calibre, who require a specialized sub-calibre drop tube to seal against narrower case mouths.
