Good thread Ken,
I'm moving a couple cartridges over to "H" extreme after years of using IMR 4350. If the published temp stability info is correct, that's all the reason I need. It seems to blow everything else away in that category.
IMR 4350 has been my "old faithful" for years though in many different rounds. I expect H4350 and the other "H varieties" to yield the same if not better results.
For all my range work, sierra's carry the load and I'm yet to be disappointed. I always have some hunting bullets (Partitions) loaded up and found that much of the time, POI doesn't change much if at all.
