I've read all the 458 Socom stuff. Not interested in the Beo or 500 Phantom. I want the Rhino in either 338 or 458. Please let us know what is going on with these and how to get one.

THE RHINO CARTRIDGE SERIES
Currently in the prototype stages, this is the latest addition to our stable. Building on the .500 Phantom concept, we have taken the same case, lengthened it and necked it down to a variety of sizes. The project sponsor was primarily interested in the .470 version, however, we felt the .338 version offered great potential and as a result we have dies for the .470, .450, .416, .375 and .338 version.
As with the Phantom, these rounds are intended for use in the AR-10 and DPMS LR series of rifles and should offer some devastating firepower. The projected velocities for a 24" barrel at moderate pressure are listed below
.450 Rhino with 300 gr Barnes X Spitzer. 24" barrel, about 2700-2800 fps (in top magazine)
.338 Rhino with 200 gr CT BST. 24" barrel about 2900-3000 fps
.375 Rhino (no bullet shown) with 260 gr Nosler BT around 2750 fps
.416 Rhino (no bullet shown) with 400 gr Nosler Partition around 2300 fps
.470 Rhino (no bullet shown) with 500 gr Swift A-Frame around 2150 fps.
