The Lock-N-Load Sonic Cleaner from Hornady takes cartridge case cleaning to a new level. Combine the Lock-N-Load Sonic Cleaner with One Shot Sonic Clean solution to effectively and efficiently remove stubborn carbon residue and other foreign materials from the entire case, primer pocket included! Tumbler units only clean the outside of the case, the Lock- N-Load Sonic Cleaner's ultrasonic action blasts carbon build-up from cases, small gun parts, and equipment, inside and out. Holds up to 200 rounds of .223 Remington cases, or 100, .308 Winchester cases to help minimize your time in the reloading room.
Only use Hornady approved cleaners such as One-Shot Sonic Clean Brass Solution or One-Shot Sonic Clean Gun Solution.
