They do, so long as there is cover. Mind you, there's a steep switch between 'mid' and 'close' range, between 20 and 15 meters where suddenly volks lose hard/rifles perform much better.
Generally speaking I would classify
0-10 close
10-20 mid
20-35 far
The performance you describe is as expected especially in cover. Bolt action rifles are supposed to be better than semi auto (carbine) in far and heavy cover.
