I've got a set of LEE RGB dies in 6.5x55 and am wanting to reload some surplus primed cases that I have. Where these are berdan primed and I dont want to remove the primer (or set it off), is this operation out of the question for the full length rgb dies? I know the deprimer isnt removable on these, but does retract. Would it detract upon hitting the space between the 2 flash holes of the berdan case or would it set off the primer and/or bust the deprimer? Kind of a whacky question, but I'd rather read to learn than learn from a potentially hazardous experimsnt.
