The HKS Model 48-K Speedloader is a manual revolver reloading accessory designed to simultaneously load six .22 Winchester Magnum Rimfire (.22 WMR) cartridges into compatible cylinders. Built by HKS in the USA, this mechanical loader eliminates single-cartridge handling to accelerate reloading sequences during range drills, club matches, and field shooting. It utilises a high-impact injection-moulded black polymer body, internal steel locking pins, and a knurled aluminium twist knob. Sized specifically for medium revolver cylinders, the unit weighs approximately 40 to 50 grams and fits standard medium-frame/K-frame speedloader belt pouches.

Key Features

  • Simultaneous 6-Round Chambering: Drops a full cylinder complement of six .22 WMR cartridges directly into the chambers in a single action.
  • Twist-Knob Cartridge Release: Secures rounds via internal steel locking points until a clockwise turn of the knurled metal knob releases them into the cylinder.
  • M-Series Movement Design: Permits slight cartridge movement within the polymer body to assist alignment with cylinder chambers during insertion.
  • Durable Construction: Combines high-impact polymer housing with metal internal components for reliable mechanical operation without external power requirements.

Who is the HKS Model 48-K Speedloader for?

  • Smith & Wesson Model 48 revolver owners — requires a dedicated speedloader built to the exact cylinder spacing of the 6-round K-frame chambered in .22 WMR.
  • Rimfire revolver target and competition shooters — requires a 6-round capacity loading device to drop six .22 Winchester Magnum Rimfire cartridges simultaneously to minimise stage and reload times.

Less suitable for: Revolvers chambered in standard .22 Long Rifle or smaller frame profiles, such as 6-shot J-frame models like the S&W Model 51; these configurations require dedicated .22 LR or small-frame J-profile rimfire speedloaders.
