[QUOTE="Stammster, post: 1939387, member: 114381"] I wouldn’t worry about temp stability unless you are shooting long range and/or at max load. With that being said, the new IMR4451 Enduron powder has the same approx burn rate as H4350, and supposed to be just as temp stable. Unless you’re in love with the IMR4350, I would try to the H4350 and IMR4451. Both IMR4350 and H4350 are supposed to be within 0.5 grains of one another. This is generally the case, but my currents lots are such that my IMR4350 is a slow lot and my H4350 is very hot. In fact I am 1.5 grains under max (based on the conservative Nosler 8 book) in my 30-06 and still seeing excessively high velocity and pressure signs with my current lot H4350 at 70F. [/QUOTE]
