Yep, we have yet another new cartridge on the market. This time it’s a rimfire round from Winchester. The 21 Sharp is a new take on the .22 LR. It does away with the heeled bullet design, which allows for a wider variety of projectile styles and materials. Winchester is claiming superior accuracy to .22 LR, and more efficient lead free projectiles.

The new 21 Sharp uses a casing pretty much like the .22 LR.
