Hi @YosemiteSam

Re the corrosion, dunno - what did you have on your fingers? It looks like some ancient ammo I accidentally spilled copper remover over. Try putting unfired brass in and leave a few days.

Leaving a spring in its compressed state is no different from leaving it in its released state - no problem either way. That's why you can leave your bolt action with the firing pin cocked and no problem - probably less of an issue than might be caused by repeatedly dry firing it every time you close the bolt and put it into your safe.

Working (alternately compressing and releasing) the spring a LOT helps, a bit. Compressing the spring to around/past its elastic limit will definitely weaken it. Or just put one or two less into it if you can do with one or two less magazine capacity. Maximum capacity of a magazine is not necessarily optimum capacity.
