FWIW: From my loading notes for a Savage 112 in 338LM, serial no. K22XXXX;

CBTO for the 300 SMK (p/n 9300T) at touch of lands was 2.976, best load was 88.4 gr H1000, CCI 250 and .040 jump.

CBTO for the 285 ELD-M at touch of lands was 2.985, best load was 86.5 gr H1000, GM215M and .025 jump

Are your measurements anywhere near these?
