I can see how those smooth lands would be forgiving on the round. It's still a little sad that they don't run the same direction. I was having to ram some paint into my pirate pistol (w/an armson) last weekend. The muzzle break has a larger bore, so the operation (drop and ram) was perfect with balls. I can see the fins catching on that setup anyway.
