I would need some more context of what I want to use it for because if it can't perform the task that I want then it is of no use, and if its overkill for the task then its a waste of powder and recoil. Take for example a 7mm-08. I would consider that to be a pretty efficient 400 yard rifle for deer size game. Its a decent balance of powder used, bullets with decent ballistic coefficients to retain its muzzle energy, and very tolerable recoil. If I change the intended task though it looks less appealing. If I wanted to hunt at very long ranges or hunt very large game I would consider it underpowered and thus not applicable to the task. If I were shooting varmints or handgun silhouette or something like that then I would consider it way overpowered and inefficient because its burning about twice the powder and producing twice the recoil than what is really needed to perform the task. For example a really popular round for handgun silhouettes was a 7mmTCU, which is a 223 case with a 7mm bullet. Its pretty unimpressive on paper, but the name of the game in silhouettes is being able to buck the wind and have enough momentum to knock over the targets, while also having minimum recoil so you don't shoot out your wrist in a long course of fire. So in that application a 7mmTCU is much more efficient than a 7mm08.
