If it cost more,It must be better
.As far as a press losing its accuracy???thats just STUPID.It is the dies that could be right for your application,or wrong for your application.The press is just a device to give you leverage.Die adjustment is what is critical to making a difference,Not the press.If a die is built relying on a presses accuracy of travel or play,,It is a piss poor design IMO.The shell holder goes up with the brass and the shellholder touches the die.Were is there a possible accuracy issue there(+ or -)??You could use a completely worn out press and still reload good ammo.BTW my challenger is still tight after ALL these years and reloads
