Thought I'd share data results from some testing I did with the Nosler 240 JHP, 23.4 grains of H110 in 1) Ruger Super Blackhawk, 5.5 in barrel, 2) Ruger Super Redhawk, 7.5 in barrel, and 3) Marlin 1894 Dark, 16.5 in barrel. I was using clear ballistics gel so I'll include penetration depth, expansion and weight retention data.
Blackhawk 5.5 in: 1307.5 fps, 20.0 in. penetration, .654 in. expansion, 96.6% weight retention
Redhawk 7.5 in: 1383.0 fps, 21.5 in penetration, .665 in. expansion, 91.1% weight retention
Marlin 1894 16.5 in: 1715.8 fps, 19.4 in penetration, .657 in expansion, 79.8% weight retention
Out of the leveraction, the 1715.8 fps was a bit too much for the nosler bullet. It didn't hold together well upon impact with the gel (little less penetration and significant weight loss)

I like those XTP's ... what kind of velocity are you getting out of the SBH 7.5 in with that load?
