CH doesn't make that press anymore, and they don't have a 50BMG press in their lineup.
I had one of those presses for a while, and sold it - it didn't have enough leverage to FL size cases unless you were 300 pounds, and all of that was arms.
There is the Hollywood, but that's a 70 year old design with almost no service, and it uses simple knee levers - so FL sizing is still a big problem, since most shooters get their brass as Mil-surp.
Of what's available, the Hornady is the choice. It looks like the RCBS, but the lock & load feature means that everything clicks in and out... the RCBS needs to tools to take it apart to change functions. /ubbthreads/images/graemlins/frown.gif /ubbthreads/images/graemlins/frown.gif
