This review critically assesses Winchester's new .21 Sharp rimfire cartridge, finding it to be a disappointment. Despite claims of superior accuracy and cost-effectiveness, testing revealed it performed similarly to or worse than standard .22 LR alternatives in accuracy and penetration tests. Its high price point further detracts from its value, making it an uncompelling option for shooters.
Two new cartridges, Hornady's 338 ARC and Winchester's 21 Sharp, have been released, sparking industry debate. The 338 ARC is designed for subsonic hunting on AR-15 platforms, directly challenging Q's 8.6 Blackout with differing opinions on case capacity and twist rates. The 21 Sharp aims to replace the 22 LR with a non-heeled bullet design, though rifle availability is currently limited.
