Gen 4 with OEM RSA. No idea on pressure, but the load doesn't feel much stiffer than 180 HST or Ranger Bonded. I am using a KKM barrel. Just went back and checked, and the listed velocity is 1,106 fps out of a G22, although I haven't choreographed it.
The Garrett Cartridges Defender .44 magnum load for the 4 inch Scandium 329 is listed at 300 something grains of hard cast at 1,020 fps, so even if this load is in the same velocity I believe it will penetrate a bear's skull.
