Back on topic here.
Speer #11 does have data for the 240SWC, but not for Power Pistol. Got any Unique, Bullseye, or 231?
Regarding OAL. With light loads you don't even need to crimp. Just remove enough flare (which should be minimal anyway) to permit chambering the rounds. Seat the bullets so that about a fingernail's thickness of the bullet's shoulder is protruding from the case. The OAL then is what it is. There should be enough case neck tension to prevent bullet jump with light loads. Watch for bullet jump and crimp if you get any. Crimp heavier loads into the crimp groove as a matter of course to help with case neck tension in preventing bullet jump..
