I think the approach here is backwards. If the subject is efficiency at long range, then consider what amount of energy you're looking for, at what range you want that energy and then go to the ballistic tables and find the cartidge that gives you the energy at X. yards. For a purely intellectual exercise, limiting the problem to only .30 caliber is okay but if you want to be "ethical" [please don't begin an argument that you can be ethical with many different calibers] then you look at the end product you want and use that. In other words, the heaviest bullet with the most velocity "reduced" by personal factors such as size and weight and recoil tolerance. Think about it.
