Starting on my first load for the new Weatherby Vanguard S2 in .30 06. Intended purpose is strictly target at this point. First load will be with the Hornady 168gn HPBT Match bullet. I have read good things about both IMR 4350 and H4350. I was leaning toward H4350, but when I went back to the LGS it was all gone. Another place in town has IMR 4350. Any reason I should hold out for the H4350? Anybody have experience with both with mid-weight bullets? I read that H4350 is less temperature sensitive. Is that really much of an issue given I don't plan on target shooting when it's too cold out or blazing hot for that matter. Thanks for any advice as always.
