I also have the .458 and love it. on the other hand, i believe the beowulf and bushy have only one factory load each, were the .458 has several. If you reload, there are alot of bullets for the socom, but I believe, and someone please correct me if Im wrong, that the 450 shoots the same bullet as a .45 long or .45 acp which means tons of bullets for the reloader. They're also lighter than most of .458 bullets where 300gr seems to be the lightet of the bullets, with exception to a 250gr barnes bullet. This is part of what makes the 450 a faster bullet. Another thing to consider is recoil, I dont know how much the bushy or the wulf has, but after 16 shots, my rra went from an extremely tight fit between the upper and lower to broke in! Although, the recoil is very manageable. I really like my .458 but sometimes I would really like to try the bushy. the wulf is big, and I hear its Bad a$$, but since finding out about the other two, I never really wanted to mess with it. One great thing about the .458, it requires no mag modifications, it uses standard .223 mags, but you have to divide the .223 shell count by 3! The 458 also really works on deer!
