Ammunition

Rules for safety and reliability

• Use ammo recommended for semi-automatic 22LR pistols
• Inspect ammunition before installing and don't use if:
• • Dented or bent
  • dirty or wet
  • old, dry cycled multiple times
• Use at least 29 grain bullet weight
• Don't use sub-sonic/quiet ammunition, it generally won't have sufficient momentum to cycle the mechanisms
• At this time we recommend against using Winchester and Browning ammunition.

Snap caps interact differently than live rounds with the Ounce® mechanisms, please follow these guidelines:

• We recommend the P2 brand of plastic 22LR snap caps.
• • If after chambering it does not indicate, cycle the handle w/o chambering to verify
• Do not reuse snap caps that have been dry fired multiple times
• Do not dry fire into a steel snap cap
• Use a swift and smooth motion while opening the handle for best results de-chambering
