What would be an HS-7 equivelant?

I have been using HS-7...and am running out. Apparently HS-7 is no longer made, at least I can't find it. Assume it was been discontinued...is there something for the reloader that is an equivelant?

  5mm,
  
  The HS-7 is identical to W-W571, which has been also discontinued. They are ball powder's, that have suggested uses of large revolver/handgun magnum cartridges like the 357, 41, 44, and 45 Win Magnums.
  
  For small rifle stuff, like the 22 Hornet, I also use a magnum pistol ball powder H-110, which is the same stuff as Winchester 296, if I am not mistaken. Lil'-Gun works well too.
  
  Best
  
  EDIT 1
  
  Lil'-Gun works well in small capacity rifle rounds, where Blue-dot, and HS-7 can be used.
  
  Best

  My burning rate chart suggests, that Accurate Arms #7, and IMR 800X, have similar burning rates to HS 7.

  How about VV N-105?

  According to the chart 105 is slightly slower then 800X or AA 7, it's equivalent to Blue Dot.
  
  
  EDIT #1, My chart shows Lil'Gun to be quite a bit slower, then the other mentioned powders. Doesn't show any handgun applications at all, as it's slower then 2400, H110 & 4227.

  There are powders with the similar slow (for shotguns) burning rates, but 571/HS7 is avery dense ball powder whose burn rate was controlled by the level of deterent coating. Other powders like Blue Dot have about the same rate of burn, but their density and response to pressure are considerably different, so while they are useable for magnum shotshells, safe loading data may vary considerably.

  lil-gun has the 410 in mind and is closer to WW296/H-110. But again, the same advisory.
