Powder for 300 win mag
Okay gentilmen, after prowling around this site for a while I've decided it's neccesary to jump into reloading. I have picked a bullet (190gr. SMK), Brass (winchester), and primer (fed 215), but I need a little help with the powder. I've read or heard somewhere that slightly compressed loads were more consistent, and was wondering which of these powders would accomplish this while being least affected by temperature?
Alliant reloader 22
If none of these will get it done please advise me on some other brand or type.
Thanks in advance
