I'm saying it's more like an assault rifle than it is like an automatic rifle. Note that in that 2-gun match the BAR wasn't being used as a support weapon (which is what the stats in CoC represent). It was being used as a normal semi-auto rifle (albeit a big heavy one).
CoC's stats are pretty approximate anyway. Why doesn't an assault rifle reroll ones for example? There's functionally no difference between an assault rifle and a semi-auto like the Garand at 100m. I don't think you can try and slice weapons effects too thinly, as long as the general effect at squad and platoon scale is about right then that's fine IMO.
