I have an old Echo press that is just gathering dust under my bench. Recently I was going through a drawer and found a bag of Echo shell holders!! I have tried Googling but there just isn't much of anything to be found for this ol' guy. Can anyone post info on the press? The shell holders I have (for the most part) are in plastic bags with a factory card listing the caliber. I haven't been able to find numbers on all of them. Another question, (on another forum - one of the few references I found), someone said the press he had used an RCBS ram so contemporary S/Hs coud be used instead of the threaded Echo ones. Anyone here done this modification? TIA!!
