yea I looked at he 50 beowulf, the 450 bush, the 458 socom. For the wulf it's got really proprietary brass and it's low power. The WSSM case is an officially produced case with good brass availability. All you have to do is buy 7mm WSSM brass and chop it at the neck. Alot cheaper. Bullets are the same at .50 S&W.
Looks like the 50 WSSM variant(whatever they ultimately call it either .50HP or 50 OSSM or something), should outperform all three of those big bore options.
