I've used Knight Jacketed .260gr sabots for ever. Those things work EVERY time, perfectly. I have a 1994MK-85....shooting 100gr pyrodex, and it is as accurate and hard hitting as anything I've ever used. I've killed deer with it from 20yds to 125yds....never lost one, and never not had a pass through with a good blood trail. I've never seen the need to even try anything else, and honestly probably never will. I can't possibly get better performance than what I get now.
