The 416 is advertised to shoot 370. Out of the box, it will consistently shoot over 400. I had a couple of my first shots clock at over 450 fps.
However, with use, the spring does settle. Once you've had a couple of hundred rounds through it, it will settle to under 400 fps, with most settling around the advertised 370. Sepulcrum's 416 settled to about 375 fps. After about 1000 rounds, mine now shoots consistently in the 385-390 range. The only modifications to my gun are metal bushings and a Modify anti-reversal latch.
