SS198LF can be distinguished by the dark green coloring on the tip.

My FiveSeveN has the 20lb recoil spring in Elite Ammunition. I can't prove 100% but a slight velocity increase should be apparent. 20fps seems to be what others have recorded. So, I'd imagine with the factory spring, we'd see close to 2090fps in this kind of weather.. **This video could contain affiliate links.
