[QUOTE="Brent, post: 5215, member: 99"] Compare the reamer dimensions to the that of the parent case, the 338 Lapua. The improvement is a sharper shoulder and less body taper, this one is also necked down of course. The drawing here uses a generic pic and is not to scale. The Imp version will make for a more efficient case and also in this case, give me 6-8gn more case capacity for higher velocity or less psi at the same speed, however you look at it. New reamers ground with the new dimensions are required, one for the chamber and another for the dies. You can have the dies cut on a lathe as Neil Jones does, which I'm doing instead of purchacing the die reamer to do the dies. Cases are fire formed to the improved dimensions.
