I can only hope they finally release a 6mm bullet with a competitive BC. The reason to use the ELD-M bullets is that they're supposed to have BC's that are high for their weight and caliber, except the 108 ELD-M doesn't do that at all.
108 ELD-M's have a G7 BC of 0.267. 110 SMK's have a G7 of 0.303, 105 Hybrids are 0.273, and 105 RDF's are 0.275. Even the 103gr Vapor Trail bullet has a 0.260 G7, and the 95gr TMK isn't far behind at 0.238.
For comparison the 147 ELD-M with its BC of 0.315 is only bested by 150+ grain bullets or the 140 RDF (0.324) and 140 JLK (0.321).
131 gr ACE prototypes had more or less equivalent G7 BC of the 147 ELD M and can be pushed ~150 fps faster from same parent case. The production run of 131 gr ACE is 0.345 G7.
Less recoil, less drop, less wind.
