Pugs, what you might consider is what ammo shoots best for you at 100 yards. The ammo you reference is subsonic and that's positive. Working against it is the truncated HP form which likely has a lower BC than most RN match ammo. Flat meplats carry baggage (drag)like that and HP designs are considered FP for BC calculation, although the meplat diameter is significant in figuring it.
OTOH, there is the issue of finding other ammo in this day and age....
