They are sure proud of that thing! (price-wise)

in a discussion outside the forum, there was an  inquiry on how this compares with the 45 raptor and I found the below pdf chart of comparisons of 45 Raptor, 450BM, 458 SOCOM, and 50 Beowulf.  Also, 458  Ham'r not intended to be interchangeable with the 458 SOCOM and seems to be slightly longer.  I too was taken back by the price...  Fascinating is how little there is on the interweb on this cartridge at present.  

From Wilson Tactical's site:

FAQ

Will a .458 HAM'R chamber and fire in a .458 SOCOM chamber? Not during normal chambering since the HAM'R case is .040" too long,  If you tried to chamber the same HAM'R cartridge repeatedly in a .458 SOCOM, the case shoulder could potentially set back the .040" that would allow chambering, thereby creating an overpressure situation that would most likely damage your .458 SOCOM rifle and potentially cause injury. 

Can you fire a .458 SOCOM in a .458 HAM'R chamber? What would happen? Yes, the HAM'R extractor can hold the .458 SOCOM case close enough to the breech face for the gun to fire, although in an extreme excessive headspace state. This is not recommended and may cause damage to the ammunition and bolt assembly.

This is according to Starline's Facebook page, "[i]t is the same length as the SOCOM but shoulder is farther forward and it uses a small rifle primer."

They lose me at proprietary parts. Doesn't seem like a huge improvement on paper to me.
