44-77 Dies

[Kurt]

The alignment between the ram and the die threads is were the problem starts. I have a rock chucker that had the ram bushing wore that gave the ram a lot of throw (slop) so I retired that press to use for a wad punch and a light duty arbor press. When I got the new RCBS I was forming .44-90 bn cases from .44 Bell basic and when running cases through the die the case lit would catch on one side this made me turn a stem with a sharp point and put it in the ram and I used a empty primed case in a sizing die and raised the ram till the point made contact with the primer with a slight dent and I was surprised just how far it was off center. There is a lot of slop in the 7/8X14 threads were the die wiggles and when the die gets locked down with the lock ring and it is not threaded straight it will hold the die on a angle with the ram also. This is were your Coax press is very precisely build for bench rest quality loads. The only die set that will top the Coax is the Wilson dies.
But man I load a lot of good loads using my Rock chucker or the RCBS Big Max that has the clamp jaw shell holder.
