I spoke with deye243 last night, about the 6x45, there are a few pros and cons from his first hand perspective. The gist is that long 223 projectiles slow more gradually, and have more sectional density which helps the further out you get in terms of energy and wind drift.
Spoke in terms of bullet weights and case capacity, the point of diminishing returns, more or less
I myself, think that for a 200-250 yard general purpose rifle, shooting around 75-87 gn maximum projectile weight, ya do get a lot from little powder and cheap, common brass. The other thing is light 6mm projectiles always seem to be available, whereas high BC 223 projectiles always seem to be harder to find
These views are MY interpretation of information gained through a conversation. Don’t hold deye243 to account for anything I’ve just said
Cheers
