The only possible advantage would be if the bullet hole was on the line between scoring zones.
Then, it's possible the slightly larger swc hole could matter.
If the match is held in the rain, for example, and the cardboard targets are wet, the RN hole could close up a bit more than the SWC hole.
But how often would that happen or help.
I like SWC and use them because the holes in the target are easier to see and they are more accurate in my gun.
There's more of the bullet to engage the rifling.
