I use a RCBS AmmoMaster with the appropriate bushing reducer (1-1/4-1 inch) for my CH4D 1 " dies. I have two top plates for my AmmoMaster, (1-1/4 and 1-1/2) and procured the appropriate bushing from CH4D direct. I also have an old RCBS Rockchucker which can work without a reduction bushing but like the added opening of the AmmoMaster for my longer NE rounds. Hope this helps.
