I have been doing a lot of research on reloading for the past six months and am just now getting ready to start loading my own rounds. I have a custom 300 win mag, 26 in barrel 1/10 twist. The barrel was bored for 190 grain bullets and the Berger's seem to work really well. I am looking for some information on what powders you all recommend. I have the Berger and Hornady reloading manuals and I have heard some good things on H4350 and H1000. Any info is appreciated.
