The 158 SWC is an all-round lead load that you can load up to 1000 FPS. Any faster and it leads the barrel.
Whether a bullet tumbles or not is more a matter of stabilizing the bullet - which is incumbent upon rate-of-twist, rather than the shape of the bullet or velocity.

Likewise, whether a bullet will "lead the barrel" above a certain velocity is a function of the material from which it is made. I've driven many cast bullets well above 1000 fps with no leading because they contained a higher degree of antimony and/or tin. HTH.

Adios,
