The original question is usually asked by someone shooting a duplex reticle and guessing holdover beyond their usual shooting distance.
Ex: A buddy in Colorado was sure my 338-06 was a poor choice for shooting elk at any distance in the sagebrush flats. "you need a Magnum!"
It worked fine for both elk at 400 measured yards but I had some holdover dots and I'd proven it in practice.
He loves his familiar Duplex reticle Leupolds and "Magnum" rifles but is unwilling to try something different...
Regardless of the cartridge, do you have a way to aim consistently at various distances and have you proven it in practice?
