The Hodgdon website shows max standard pressure load of 3.8gr Titegroup gives a 158gr LSWC 920fps at 15,400 CUP in a 38 SPL case with a 7.7" test barrel. Hodgdon doesn't give +P loads for lead bullets, which bugs me.

As I recall, the max CUP for 38 SPL +P is 18,500 CUP, so I'm quite confident 4.0 gr of Titegroup would be ok, and might hit that 829fps out of a snubbie.

I have to say I didn't know Titegroup could be loaded that aggressively in 38 SPL, and it makes me think a 158gr Rimrock soft LSWC-HP over ~4 - 4.2 gr of Titegroup might be a very good short barrel 38 SPL self defense load that gets dang close to the FBI load.
