shotgun extraction problem!

I would also look into polishing your chamber if your somewhat handy.

Chuck up a shotgun cleaning rod into a drill and wrap 0000 steel wool around a chamber brush.
You can use oil,I personally like to use mothers mag & aluminum polish to help smooth things out.
Keep the rpm's low and don't score your chamber with the knurled portion of the cleaning rod (wrap with electrical tape).
 
It's the base of the shell that causes the problem.

If you use a magnet on one of the shells you will see that the base is made of steel.When the shell is fired in the chamber it will obturate to the dimension of the chamber but unlike brass it doesn't spring back quickly.
This is what causes extraction problems in roughly cut chambers.After a good polish on my chamber I've had had not a single problem with many of these shells.
 
Remington and Federal use the same types of low brass material in their cheap target loads and dont suffer from the same habitual problems.
 
Stay away from that Winchester Target ####. It has extraction/ejection problems in ALL shotguns. It's ####. Stay away from it.

I shot that Winchester Universal stuff without problems in my Fabarm Pro Forces and Mossy 590A1... Unsure if the target loads are different, the stuff I have is #4 lead shot, 2 3/4. I have 75 shells left so I'll try it again and see what happens.
