I've shot Tony's HS-6 load with the 158s, and find it to be as advertised:
4" GP-100: M 966.5/ES 83.28/SD 32.77
3" S&W 36-1: M 887.0/ES 29.15/SD 11.40
2 1/8" DS: M 841.4/ES 24.07/ SD 8.88
This is right there with Bryan McGilvray's "TX FBI Load" (using Unique) in usefulness. A max load of Power Pistol works well also, but is flashy in the dark (the Unique load is not - can't speak as to the HS-6 loading on that issue). Here's a link on the PP performance from Pete's forum:
