[malachite]

i dont know about charts and such but i know that when my friend put a new spring in his gun at first it was shooting really hard.. we figured that was because it was new and wasnt warn in yet..

he had shot me in the leg right after he upgraded it and caused me to bleed we did the same thing a couple days later after firing it a bunch.. (but on a full batery now) and it just left a welt..

so ya.. i think it might just be begining tensile strength in the unused spring
