History
[edit].21 Sharp was announced in September 2024 by Winchester Ammunition and was released in 2024.[1][2] Initial factory loads for the .21 Sharp include a variety of bullet types such as jacketed hollow point, copper‑plated, full metal jacket and lead‑free copper matrix options, demonstrating a broader selection than traditional .22 LR ammunition at launch.
Design
[edit]The cartridge was designed to shoot a copper jacketed bullet using a .22 LR case as some jurisdictions ban lead bullets.[1][3][4] Winchester marketed the .21 Sharp as offering improved accuracy and reduced felt recoil compared to standard .22 LR ammunition, highlighting its appeal for small‑game hunting and precision shooting.
