What animal at what distance, specifically, do you believe can this over-book load for 7-08 load harvest which isn’t also done with a .704G1 BC 153 A-tip at 2750fps??? (Of note, the 153 has an SD of .313, with the 175 7mm also at .310).
Again, nothing, and with no difference in effective range.
Also again, don’t sell this difference as something it isn’t. The 308 case and the Creedmoor case are standard bolt face, short action cartridges pushing very similar small bore bullets of similar weights to similar speeds. Distinctions without differences.
