I don't want the spring under that stress for long periods, so I don't replace that seventh round after chambering it.

Yeah I know what you're thinking - I'm a wuss so I think the spring is a wuss too. Hah.
Don't over think it. Springs wear out from use not from compression. A lot of mags in 45acp tend to be hard when inserting the last round. All my Glock 21 mags are like that yet they never failed
