Finally had a chance to go out and try my Nordic spring. I cut the spring 6 inches longer then the S&J spring. Ran 100 rounds loading and unloading the gun to practice twins loads and not one single last shell stuck on the lifter . The spring tension feels harder. The next step I will measure spring tension with a weight and see witch one of the 3 as the softest spring. Then I will make a video of the Nordic spring and S&J spring. I can't wait to try this extension on another versamax because apparently I'm the one only one with this problem. Last night just for fun I swapped the s&j spring back in the tube without the 2 inch plug inside the tube and this spring is weak, I had 3 shells out of 18 bind on the lifter because they weren't slammed hard enough at the back of the lifter. IMO your spring just needs to be 6 inches longer.
