Very cool! I'm looking forward to seeing the finished rifle. .
Pics sent to ya Terry, I trimmed the cylindrical brass to 2.490" as is, necked brass down in the 400 Whelen [Petrov] die to a snug on closing fit, locked die at that length, primed, formed, and ready to load cases measure 2.495"
Ran outta daylight for chronoing, but will get to that asap.
