I agree that this is more than likely the same old FBI load with a new box (and probably a new price). AFAIK they always sealed the primers and bullets with waterproofing and they always used a soft lead bullet meant to expand. So what's new??
There is however a MISTAKE with the technical data that is posted on Midway's site. They state the velocity is 945 fps yielding 248 ft lbs. of muzzle energy. For a 158 grain bullet moving at 945 the CORRECT muzzle energy SHOULD BE 313 foot pounds. So ....... either the velocity or the muzzle energy is incorrect.
That said..............
Buffalo Bore has the same configuration and weight bullet available NOW. To compare, out of a 4" bbl. Vel. is 1162 ft/sec. and the energy is 474 ft lbs. which is low end .357 Magnum ballistics and blows away the Remington.
