The ballistics come form the RCBS Load ballistics program. Chronographing the load ishows 2150 fps out of the 12" pistol, and 2694 out of the 24" rifle. The Nosler 120 gr. Flat Point bullet which is used in the Federal 7-30 Waters load has a ballistic coefficent of .195, the Ballistic tip is .409. more than twice the factory load. If you can get a Hornady 4th edition manual, you can see the data for a rifle and a Contender, the rifle data is only with the flat points because they are necessary in the Winchester 94 rifle. The contender data can be used in anything that will accept pointed bullets. Take the Contender data and add 25 fps for each inch of barrel and (24"-14"=10 inches difference, 10x25=250fps, 2500+250=2750 fps.) now that is not quite exact because the chronogramp only shows 2694 fps average. If you don't reload than you are stuck with the factory bullet, or getting someone to load them for you. I hope this helps, but flat points are the pits ballisticly. The only place that will show this is a loading manual, Ballistic program or the deer in the field.
