That's interesting, so with that twist and length combination they're not gettng driven a full rotation before clearing the rifling. I wonder if there's an established formula that applies in respect to that. Mine is a 16" 1/8 so my 240SMKs get almost two full driven turns. You're still getting good accuracy though, can't be too much of an issue.
