Most battle rifles are just harder for the average person to control because of the larger cartridge. Some are relegated to semi-auto but those are usually purpose built platforms such as a marksman rifle.

Hmm, just looked it up and there are battle rifles with full-auto and a built in grenade launcher, it probably would surpass the assault rifle then, presuming you could compensate for the worse handling.
