if it's sealing perfectly it's that's the upper end of what a 100 does and the lower end of what a 110 does when it's leaking though it depends on the maker of the spring. a guarder sp110 shoots 390-410 for example. And in the case of my m14... 420 :P

I think we had a shs 110 put into a teammate's ka m4 and it's at 380~
