It seems like it.
Factory rifles from Savage and Ruger are offered in .450BM but not in .458Socom nor in 50Beowulf. When you see an AR cartridge offered in bolt guns by major players, it has some real legs to it.
Brass for 450BM is offered by Starline and Hornady. The others? Either the inventor of the round, or Starline (Starline apparently makes everything).
I'm not saying 450BM is the "best" only that it seems to have won. Sort of like Betamax vs VHS. VHS was technically inferior in almost every way and still won.
IMO, a big-bore AR is a challenging "tweener" because it's really the worst of two worlds. The pistol caliber .452 bullets are all design for slower speed ranges (in general) typically associated with a 45LC or .454Casull. The .458 bullets are intended for a larger case with a bunch more powder.
I'm hearing good things about some bullets in 450BM though, especially the Deepcurls and the Barnes bullets, which seem to hold together well at the higher speeds not possible in a revolver.
