Thread: 4895 vs 2206h

IMR4895 was developed in the 1930's for the .30-06 Garand rifle and is more temp sensitive than AR2206H so two different powders. IMR loads have increased substantially over the last 50 years for whatever reason, possibly the different pressure measuring system.

So then the power being more sensitive, would it perform difference in different situations? What situations? Does this make that powder less usable over a range of hunting environments?
