930 JM PRO spring length

I have the Mossberg 930 JM pro 24" 9+1 12 gauge. What length of spring are you using with the Nordic MXT+9?  With the stock length spring from Nordic it won't reliably feed from the tube, I trimmed 3" off and it works 90%. I tried the spring that came with the original gun and it took 15 in the tube but didn't feed for crap. I don't wanna cut too much off.

Did you get the regular spring or the heavy spring?
 

My experiences go against the advice of the little piece of paper/sticker that comes with the spring. I think mine sticks out only a couple of inches past the end of the tube. Once spring pressure got so high, we needed to polish and stone (and maybe recontour) the shell latch because shells were sticking. If the spring pressure is enough to pop the shells out, try polishing the latch.
