I do a lot of hunting with my 300 WM in very cold weather. Do the Hodgdon extreme powders live up to their promise. How much difference do you see in temperature sensitivity between H1000 and RL 22.

elk hunter
you will find the hogden powders quite temp insensitive R22 as much as i love this powder for the velocaties i can get with it in my 06 both with 180 and 200 gn partitions it is pretty temp sensative
i would stick with the H1000 its a good powder fot the 300 s

Thanks.

Depends on the cartridge you use them in.

Sometimes they are insensitive, and sometimes they are as temperature sensitive as any other powder.

They are good powders, and I use them a lot, but they only live up to their advertising claims in a few very specific instances.
