Manufacturer Tips

• Ammo: Use round-nose loads from Federal, CCI/Blazer, or American Eagle; avoid hollow points for best feeding.
• Spring tension: If feeding is too fast/slow, adjust tension per the manual to match bolt speed.
• Bands & dummy rounds: Includes clear rubber bands; internal black dummy rounds are followers—do not use as ammo.
• Rotor care: Do not pull the rotor counter-clockwise and release; this can damage internal followers.
