For SST and sometimes Eldm, best lengths I have found are typically somewhere 2.245-2.265 (they don't mind the jump), so while your OAL is close to that, have you tried varying the OAL at 31.0 grs to see how the grouping responds. I do groups differing by 0.010 to see any discernable improvement/worsening, to settle on an OAL.
Using the Hornady gauge and bullet comparator tool, from base of cartridge to lands my barrel is 1.71", The ELD-M is 1.67" to ogive and the Frontier is 1.64" to ogive. So I am looking at 0.040" jump with factory loaded ELD-M/SST, 0.070" of jump on the Frontier, and 0.010" jump from my loads.
