What is the difference between Bell brass and the others? Thanks

Not much different than Hornsdy; they're both goog. In fact, I wouldn't be surprised to read somewhere that Bell makes Hornady's for them. I think they make 416 for Remington.

I've used the Hornandy brass quite extensivley as well as the Bell brass for my .458Lott. the only difference I can find is the Hornandy is $21.99 per 50 and the last time I bought Bell it was nearly twice as much!!!

As surestrike stated, the Hornady brass is both cheaper and plentiful. The BeLL brass sometimes suffer machining differences that will prevent your chambering the loaded round. I've used the first box of brass that started out as factory loaded rounds and have reloading those 20 pieces 7 times without any problems so far. A full half of my loads have been with plinking loads that will extend your brass life immeasurably.
