If “.020” CRTO” wasn’t a typo anywhere across the board, then the only thing which might make sense would be a poor choice of vernacular to represent “freebore”. So .020” from the case mouth to the start of the throat. But I have never heard it called CRTO before, and could only speculate it is “case rim to ogive,” but honestly, if that IS what they meant, I don’t know that I’d buy from them.
