.....FWIW, over the years one particular aspect of reloading that has stuck with me was to ensure sufficient amount of bullet was seated in the neck of a cartridge to securely hold it to prevent setback, tilting, etc. Granted it may be an "old" concept borne back in the day before the advent of super long and super sleek bullets. This was reinforced during my foray into 300blk and flatbased bullets were the more common format for 100-130gn bullet weights used in supers.
...the other thing I've learned over the years is that the popular recommendations for seating depths and amount of jump don't always apply, it comes down to individual barrels/chamber and the only way to determine what is "best" for achieving ones objective is to test, just no way around it. Sometimes the objective itself needs to be reassessed, i.e., is it realistic.
.... to the OP, if the bullets in question aren't being jammed into the lands at their longest possible COAL, while having sufficient bullet retained in the case neck and don't exceed the magazines internal COAL allowance....then I'd just start at that longest allowable COAL length regardless of the amount of jump, test and work backwards as required.
...BTW, I'm a gasser only user/reloader so my remarks are based strictly on MY experiences loading for my gassers...
