The following comment was appended to the above link:

Chief Says : Very good lesson , But lastly one needs to relieve the shaft spring tension. After the shaft is tightened , one needs to back off the tension by turning the shaft 1/8 to 1/2 turn counterclockwise.

I have noticed " especially on my max tensioned " magazines , ones where the hexed head nut is turned as tight as it will go. If you dont relieve the shaft tension a bit ( 1/8 to 1/2) turn, sometimes the rotor/spring/ammo will jam just like a weak "poor adjusted" magazine.

A good test = If your favorite magazine gives you trouble after you have
done the prescribed adjustments and cleaning , grab your allen wrench next time you go shooting or to the range. When your magazine jamms - turn the shaft with the allen wrench 1/8 turn counterclockwise. WOOH ! WALLA ammo now feeds fine again.

RELIEVING SPRING TENSION = IS A MUST DO WITH THE 10-22 MAGAZINE.

It's certainly been common for me.

I found the procedure a few years ago on http://www.rimfirecentral.com for cleaning and re-tensioning stock 10-22 mags.

I'll see if I can come up with it again.
