Double feeds in a semi auto

[solz]

As the title says,

 

Jus wonder what causes double feeds in a semi auto, as in two cartridges are pushed out of the mag tube instead of one.

 

Is the problem caused my cartridge length? Or a fault spring/catch or so other mechanically failure?

 

Thx

On certain makes it has been reported using cartridges that are too short ie 65 mm case length, might help if you state what s/a it is.

On a Remington 1100 it is caused by the interceptor latch/spring malfunctioning. Take it outside and turn it upside down and you should see a small latch that moves up and down when the action is worked. It stops more than one shell from exiting the tube.

Cartridge length will play a big part , try to use minimum 70 mm .

I think shell stopper is not working properly. Maybe gummy oils or bent lever and/or bad spring tension. Try to clean the stopper first(wd40 etc). Good luck.

Use 3in1 oil
