Too much spring?

Bob Sanders · Jul 22, 2013

What happens if the mag tube spring is too long? Besides not loading to capacity. I can run 7 now, but if I load 9 it double feeds after first shot.
Thanks!

You gotta trim it down. What capacity tube r u running? What capacity should your gun have with the tube?

How much does the spring stick out of the mag tube?

10-12". Start at 12".

Bob, if your shell latch has been tweaked, they can sometimes be tweaked too light. I had to give mine a tiny bit more retention (bend it back a little) or it would sometimes not retain the last shell going in the tube when dropping deuces or quad loading.

It holds 9 and I can load 9, but last 2 are a bit firm. New Nordic spring trimmed to 14 inches past end. Factory spring balled up and kinked in tube. Nordic spring is stronger, larger wire and looser coils. I polished shell stop face and cleaned up extension tube joint as well. I think I'm close.

14" should be fine. Are shells slipping past your shell catch?

Sounds like your shell catch isn't strong enough.
You may have tweaked it when you polished it.

Maybe slipping past. How does one "de-tweak" it? Stretch the spring behind it a bit? Or try to get a replacement? All I did was take it apart and hone the face, which it appeared to me that it needed.

Hell, there may even be a shot pellet stuck in there. The whole thing locked up when it loaded a leaky shell. I thought I really screwed the pooch, only to find a bunch of shot in the trigger group.

Yeah, pull it apart and see if anything weird's going on. To de-tweak it you just bend the retainer end (only a little!) back toward the centerline of the shotgun. I don't know what a latch looks like in a 930, but a Benelli has two u-shaped cutouts that the catch will bend at.

I did notice the shell stop didn't seem to extend onto the mag follower as much as I remembered after I reassembled it. Gotta get'er done, I'm shooting Sunday! Or it's going to be 870 time!

If there's not anything foreign behind the shell catch, makes sure the spring that drives it is properly seated or whatever before you start bending. Good luck!
