Littlestone .357 Magnum 187gr Hardcast

  It's on sale BTW. Comes in a neat box with a 1460 FPS 8" barrel rating.

Those look nice, I wonder of they may have something besides H-110 / 296 inside?  MP 300? Other?

Looks like a Ranchdog TLC359-190-RF mold.

    They didn't do near as good out of a 6" barrel.

Ruger GP100 6" 1223, 1300, 1252, 1263, 1271. Average = 1257.8 FPS/ 657 LBS

My RCBS 180gr Sil Gas checked did better than those @ 1320 fps

357 Mag 11.0 gr Blue Dot 6" S&W 1320 fps

Intercooler's  Ruger 4" GP100 @ 1237, 1234. Average = 1235.5 FPS/ 610 LBS.

That's a very good hunting bullet too bad the load didn't live up to  their velocity claims. I load the same bullet over 17.5 grains of pp300mp. I haven't chrono'd these yet but Brian Pierce claims 1420 fps from a 6" GP100 with this load.

Wonder if their 8" barrel is like a TC rather than a revolver.
