I haven’t tried jacketed bullets, but I would assume they would have reasonable expansion at the velocity they are doing at 200m with normal loads, but this is probably well above subsonic.
I would try emailing Sierra.

Same for me with trailboss and 151gr 308 casts. We clocked them at 1050fps if I recall.
