Hi everyone,

I would like to find a reliable way to stiffen the weak springs in the Remington autoloaders. Over time they tend to weaken and other that forking over 50 bucks I would rather find a non bubba repair that will allow for reliable cycling.

Any ideas out there ?

Thanks all

Gabe
 
Leaving a spring under load does not weaken it. Repeated cycling, extreme temperature changes (think hardening and tempering type temps) and corrosion will weaken a spring. Stretching the spring will just make it longer and will do nothing to the spring rate. Lessons learned from airgunning with springers.

You could shim the spring so that it is compressed more when fully loaded but the spring will continue to weaken to eventual failure. This will help feed all of the rounds in the mag assuming that is the problem. Not feeding all the rounds that is. Shimming will take up room though and you may not get a full mag. Best to replace the spring if it is not doing its intended job.
 
leaving a compression spring under tension, will infact, weaken it. if it is left long enough. valve springs that are left under compression for to long will not come back to there original hight and preasure, ever
 
I know nothing of valve springs... or springs of any kind for that matter, but I did see a demonstration of this very topic.
A couple fellas debunked the theory that leaving mags loaded weakens the springs.
They pulled a bunch of surplus M1 carbine mags that had been loaded for 40+ years and they functioned flawlessly.

They went on to describe the theory in scientific terms that I followed only as long as they were speaking them to explain exactly what Tinner4 said.

Magazine springs wont weaken if left loaded, repeated use weakens them.

a spring is a spring. ive seen valve springs go south in as little as a few years if left under full compression. personally I call BS on the carbine spring thing. pull the springs and see how much shorter they are while not under compression compared to a new one
 
I'm a firm believer in springs don't weaken from being tensioned it's the cycling that wears them. However, with magazines, I've seen feed lips bend under pressure being fully loaded for so long cause issues. Valve springs a very different story because they are being introduced to different wear conditions, there's heat, high RPM, even the design of the valve train its self. You are also right though they won't come back to the same install height, that can also be a symptom of wear and being cycled. I can understand what your saying, I just feel comparing valve springs to magazine springs is not a great comparison. I had a 77 Ford F100 with a 300 straight 6 six that sat for at least ten years before I got it, no issues with weak valve springs, even though one of the rockers had eaten a valve so bad it was riding on the spring retainer.

Another way to look at it too is magazine springs are always under a bit of tension, I've never come across a magazine that the follower was loose in the magazine. Just a thought. Not trying to start a war here just throwing my two cents into the ring.
