Has anybody loaded Magnum powder for the .300 Win. mag., 180 Nosler Partition ? Velocity/accuracy? Most importantly, how does it compare to The Hodgdon Extreme powders in being insensitive to cold temperatures ?

I tried the powder with the 168's and got great velocity. I have no other experience with it except for the load work up. I went with another powder because the Magnum seemed extremely dense and slow burning that I could get more loads out of a pound of some other powders.

I think it's a good product and would use it in my hunting loads. I was getting 3250 fps out of the 168 grain bullet with good accuracy.
