I have more than 3 in some caliber families (as you know). Just because I remove a portion of the base has no impact on how much the shoulder is bumped back, thats entirely dependent on what the base to shell holder distance is at the top of the ram stroke and nothing else. By grinding off 0.005, I'm not altering the internal physical dimensions of the die or impacting it in any way other than allowing more latitude in bumping a shoulder, if necessary.
If I'm loading for Tom's 308 Hart barreled rifle, I use a previously ignited case to determine proper headspace, FL resize one and check it in the firearm right then and there to insure the bolt closes properly. If I reload for my Savage, I do the same or for Linda's Sako or Rod's Remington, the procedure never changes. The length of stroke on the ram to the very top (and the coarse adjustment of the die body) does change.
No 2 production rifles headspace the same due to tooling inconsistencies among other factors, so, it becomes a matter of setting correct bump for each rifle. I don't mix (and neither does the group) loaded cartridges between like caliber firearms. If, someone in the group or myself buy new unfired factory rounds, once they get ignited, the empty brass is the segregated to that particular rifle/handgun and stays there until it becomes unsafe and then it gors to Omni-Source.
