    H4350 was the only powder I could find during the powder, primer and ammo shortage scare and I have about 6 lbs to use up. Want to load a 270 WSM with 150 grain Partitions and hopefully the H4350. The Hodgdon site says it is ideal for the WSM but my Nosler reloading book does not show it as an option. I am only trying to reach out to 300 yards for deer and elk.

    I used 58gr of H4350 with a 140gr accubond through my 270WSM and got 3051fps average with good accuracy. I had the barrel cyoaccurized because it was fouling quickly and my accuracy with that load ended. My speed increased 130fps after the cryo but I had to switch loads to get my accuracy back. 62.5gr of H4831 with the 140gr accubond is shooting good. I haven't had a chance to chronograph it yet.
