Lots of hunting rifles have an internal magazine with a smallish fixed capacity.
That's functionally quite different from a rifle with easily swapped external magazines with high capacity.
Chambering also matters a little bit. Weapons with a military lineage tend to have smaller rounds than rifles for big game. The smaller rounds make it easier to pack large amounts of ammunition and reduce fatigue.
Of course assault rifle is a meaningless term, but that's a result of many efforts to warp the discourse and not because the weapons used for war are literally the same as a weapon that is sufficient for hunting.
