Double Feeding Without a Return Spring - Fact or Myth?

10 June 2012 - 10:55 PM

While servicing several of my markers today, the topic of double feeding without a return spring on a cocker came to mind.My pump stroke is ultra smooth/light - a double feed has never occurred simply by running or sprinting without a return spring. I've read multiple posts about markers double feeding while running due to the pump handle moving. (Nothing will prevent double feeding if the pump is forcibly hit while sliding/diving etc) I've always been skeptical of this, and decided to actually check it out. Turns out to be an Urban Legend. With a properly adjusted cocker, it is almost impossible, and have the pics to back it up. Even with a force-fed hopper, I've never had that happen. Double feeds only occur with a weak detent or user error. If a normal paintball could fit between the bolt and the breech in pics 2-4, or enough to get chopped, the pump handle is being pushed against by more than just the forces of running, or the paintball is deformed. To open the breech further (in pics 3&4) by just running is impossible. At that point, the main spring is under high tension with the marker cocked.
