Basically that's the question. Will keeping my shotgun fully loaded lead to the weakening of the spring and lead to problems cycling?

I just fired a mossberg 12 gauge that was stored fully loaded for 20+ years.
no problems.

The most prevalent opinion shared by many metalurgical engineers is that springs are affected more by continual loading and unloading, rather than having a constant load at or near capacity. Over compression is bad, over extension is bad. Some magazines do push the limit on compression. The suggestion is to load full capacity -1.

If you have a spring that "takes a set" after a few years of routine use, it was a badly made spring to start with, it does happen and there is no sure way to tell which springs are poorly made except to buy new from a reputable source to keep risk to a minmum.

Thanks that was some really fast and really good responses. It was only like 10 minutes.

Very good to know on all accounts.

I have have heard people concerned about this same thing in terms of their AR magazines. I have never heard of any consensus being made. I was definitely thinking of keeping it loaded under capacity but I was thinking of going a little overboard for the sake of security--thinking that having 3 or 4 rounds would be better than having to load it up in an emergency (or possibly not having it work at all). -1 or -2 is a much better option for me.

Please if anyone else has a story to tell by all means share it . . .

same holds true for mag springs.
another gun in the 20+ year collection is a winchester 1905 with 4 of the 5
35 cal rounds in the magazine. fired w/o a hitch. (except i didnt save the brass and found out the ammo is impossible to find!)
I keep all my semis -1. No valid reason, just habit.

Awesome . . . where did this 20+ collection come from?

My mother in law offered them to me. she said they were "grandaddy's old guns". have been setting in soft cases in the hall closet all these years!
