after all the ballyhoo from henry how they take care of problems with their firrearms, that e-mail just plain sucks. maybe a phone call to a higher up in the company will get results for you.

I agree. I'm pretty disappointed with that email. Actually it plain p***ed me off. After some (polite) back and forth, the general message I received was 'if you leave it loaded expect to buy a new one every 6 months or so'. I also received some ridiculous attempt at an analogy about how when you use the brakes on a car, they wear out faster. And repeated mention of how other customers have this same problem. I've not been conversing with a firearms enthusiast here. But she did send a new mag tube without me actually asking for it. Probably to try and get me to stop caring about product quality and go away.

I made it very clear that Henry should care more about performance than this, and if she didn't forward everything to her supervisor or someone higher up than that, I'd be calling about it.

Very odd response --- yea, NOT what I'd expect.
Given the number of times I've seen threads on gun forums regarding the longevity of magazine springs, I'd offer the opinion that many people don't understand how good springs work. As said, good ones wear out through cycling, not static compression or non-compression. It's possible, I suppose, you spoke to someone at Henry like this. Still, someone at Henry ought to be knowledgeable about this.

Don't give up. Your situation should be made right. Speak to someone else --- even the owner himself -- just as you intimated!;)
 
Might just be that spring being poorly *tempered*, might not.
Temperature within human tolerable ranges should matter not a whit.
Re-stretching is a *one time only* scenario in most cases.
*Muzzle-up* is an old, time proven method of coping with; weak, lost or failing springs and fortunately is a moderately intuitive manner in which to cock a lever-gun anyhow.

My take: Get the replacement and the NEXT replacement at the same time JIC.

My Marlin 39 has been loaded for years at a time beside the fireplace and has yet to fail in decades so spring failure-loaded is not a forgone conclusion.

Update:

A new mag tube has been sent out. As per my request with my initial contact, all the emails were forwarded to a supervisor, who called this morning and left a message.

I returned the call, and she explained that because of the production line assembly they do occasionally get faulty components and it sounds like I got a bad spring. She checked to confirm a replacement had been sent, and also confirmed that their springs should not fail from simply keeping the magazine loaded. I asked what to do if the new one fails, and she said to just call her again.

Now, that is the level of service I expect from Henry.
 
Springs under a constant load (but below the yield strength) experience a slow plastic deformation called relaxation. See here. This deformation takes place faster in new springs, and quickly levels off. Gun manufacturers sometimes take this into consideration, and make their springs overly strong to compensate for this loss to extend the magazine spring’s usable life. That’s why sometimes it’s tough to squeeze all the rounds into a new magazine, or why some old magazines won’t feed all the rounds out of the magazine. My .357 Henry, which is a few years old, would only comfortably hold nine rounds when it was new. Now it holds ten, but still feeds fine.

The metal strength, composition, and heat treatment of the spring has a lot to do with exactly how much deformation takes place. Some metals and alloys retain their shape and strength more than others. On a side note, stretching the spring back to its original length is only a temporary fix, since by stretching you are causing further plastic deformation; further weakening the spring.
