Dakota Nut5.....I recommend Hodgdon' s reloading manual in hardcover. It has three companies powders in it and I' ve found it to be in tune with all my rifles.

Other really good manuals is Hornady' s and Lymans....Speer' s is fine too.....Nosler' s has left me wondering a few times and I have no experience with Speer' s manual.

30-06 cases can be fired five to ten times and the first sign of loss is a split neck or a ring around the case about 1/4" foreward of the head of the case. This ring is caused by headspace and is not dangerous.....however if the case is not discarded when the ring appears, the case will break in half in the chamber and leave the foreward end of the case in the chamber when you eject the case. It comes out easily but it' s not something you want to happen on a deer hunting trip.
