I don't think they make a 117 in the .257. For the .264 they have oneThe old Speer number nine manual shows a 87gr at 3623 with58 grs bullet of Imr 4831 and 3386 with 55 grs of Imr4831 with the 100 gr remember a mono bullet allows you too step down in weight the 25-284 should shine with the 90 gr absolute you will get a big velocity gain with that bullet over a conventional cup and core unless you plan on shooting past 400 yds I would take a look at the 117 gr absolute if you have the right twist I think off the top of my head at least a 1-8.5
