Calico .22LR Drum Magazine Tips
back to Calico fan site home page


The helical-feed magazine must be loaded through the feed lips, one round at a time like every other .22 magazine. Loading 100 rounds may sound tedious, but is less so than loading ten rounds ten times. Also, the magazine is equipped with a spring release, so the rounds may be inserted into the magazine with no spring resistance.

To load the magazine, first release any spring tension by pushing the spring release button in the center of the winder.

Always push the spring release button in quickly and push it in all the way. Doing it slowly or partially will cause clutch damage.

Then turn the winder just enough to make the follower visible in the feed lips.

Load one round by pushing the rim down against the follower until the rim can slide back under the feed lips.

Repeat the procedure until the magazine is fully loaded.

You should push the spring release button 2 or 3 times while loading, as the tension buildup will somewhat hamper the loading process.

Also, if resistance is encountered while loading rounds, tapping the front end of the magazine into the heel of the hand will help keep the loaded rounds compacted and aligned properly.

NEVER FORCE A ROUND INTO THE MAGAZINE! The magazine can be seriously damaged.

After loading 100 rounds into the magazine, turn the winder through fifteen (15) complete turns. There is a raised line on the back of the winder to help you count the turns. If your magazine has a swing-out crank handle, the counting is natural.

CAUTION: DO NOT OVERWIND THE MAGAZINE! Although the torque spring is designed to survive 100% overwind, overwinding may damage the spring and will significantly increase the force necessary to strip a round from the feed lips.

If the rotation of the cartridge carrier seems sluggish, or if the rounds fail to feed properly, it is most likely due to excessively lubricated or dirty ammunition. Use only CLEAN ammunition for good results.

General Tips

  • Always use high-velocity .22LR ammunition in your .22LR Calico firearm. If your ammunition is not powerful enough, the firearm will not function & feed properly.
  • Never attempt to spray lubricants into the magazine. The .22LR ammunition itself is lubricated, providing all the lubrication that’s needed for the magazine.
  • Always be sure the firearm is unloaded before working on it!
