I too like and use H-4895 powder In a .223 Rem, a .308 Win, a .358 Win, and a 35 Whelen. With the exception of faster burning powders,I am sticking to my story with the 4350's, 4831's, etc. The story I told is backed by fact. Hodgdon is not the only game in town with regards to cold weather performance. The Ramshot powders are by far the cleanest burning powders on the market, the extreme powders are some of the worst. A spent case from a Ramshot load looks like it was flashed over a candle. It doesn't look shot. Cold weather stability does not always translate into high temperature stability. The newer generation of ball powders will eclipse the stick powders very soon. Play with the Hornady super performance stuff. A 165 in a 22 inch 30-06 going over 3000 fps and into an inch or so with factory fodder. And they are stable right across the temperature board. When these powders are unleashed, they will revolutionize reloading.

Daryl, where did you get pressure data for a .450 Alaskan? I too have obscure books on arcane calibres, but none have pressure data on this calibre.
