The thing is that 200 guess is based solely on how much it hurt when I shot it at my foot. I read someone who also had this same springer on another website claim it at 180, then a post after say 250. So I imagine it depends what rusty spring they pulled out of the garbage at the factory.
EDIT:
Wait, I forgot to mention my 200-220 guess is based on .12 it came with So .20 would be at 170-180. Which explains the discrepancy.
