Armscor manufactures distinct .22 Short and .22 Long Rifle (LR) rimfire cartridges. Note that .22 Short and .22 LR are different cartridge lengths; a .22 Short has a shorter case and less powder, meaning standard .22 Short ammunition will not reliably cycle in most firearms built specifically for standard .22 LR. 

Armscor .22 Short Specifications

• Bullet Weight: 29 grains

• Bullet Type: Solid Point (lead)

• Muzzle Velocity: ~700 to 950 fps (approximate, low noise/recoil)

• Use Case: Quiet backyard pest control, gallery shooting, and compact vintage pocket pistols or revolvers. 

Armscor .22 LR (Long Rifle) Specifications

• Bullet Weight: 36 grain (Hollow Point) or 40 grain (Solid Point)

• Muzzle Velocity: ~1,247 to 1,260 fps (High Velocity)

• Use Case: Target practice, plinking, and small-game hunting. 

Performance and Availability

• Compatibility: Always check your firearm’s barrel stamp. While a rifle or revolver chambered explicitly for .22 Short can only shoot Shorts (or sometimes Longs), a .22 LR chambered gun can technically chamber a .22 Short, but it generally will not cycle semi-automatic actions automatically.

• Pricing & Market: In local Philippine markets, Armscor rimfire rounds like their short or standard offerings run around ₱7.50 per piece depending on the supplier.
