Thanks, would you have the length to ogive ,

Unless you have the exact same comparator the dimension is meaningless.  Unless there is another way of measuring cartridge base to ogive I am not aware of.

As Garyw says, best way is to give a couple of dummy rounds to the gunsmith and hope he is able to measure and replicate that dimension.   Keep another dummy round to check yourself if he screws up.
