    I have a good amount of H4350 and H-1000. Everyone looks to be running H-1000 or RL26. Will H4350 work for 143 to 156 grain Bullets?

    I'm sure you could find a load that'll work fine using H4350, but you could very likely pressure out before you reach the velocities of RL26 and H1000.

    Running the numbers through QL, for the heavy for caliber bullets, N570 appears to be the all out velocity king without getting into excessive pressures.

    If that's the only two powders you have to work with.
    I'd go with the H1000. You won't get the case fill with the H4350 without going over pressure
    is my guess. ( as B23 said)
    A friend of mine is running the RL26 and the Berger 156's with really good results.

    H1000 and smk 150s work so well for me I didn't seriously test anything else. Tried RL 26 just to satisfy my curiosity. It gave about 50 fps faster velocity with less accuracy.

    BBD82734-8BC7-4F4D-ACD0-A4E0A81B2952.png This list is from the load data sheet on Warner tools website. It is a partial list and for their 121 flatline, so I would start low and work up with caution. I’m sure you could find a load that will work with h4350, but will it do what you want accuracy and velocity wise I have no idea. I’ve used Norma mpr, h1000, and rl26 with good results.

    From not only my experience with 6.5PRC but valid data on powder and charge I would say leave the H4350 out of your choices.
    H4831 is a pretty good option but, all in all, the PRC needs slower powders than H4350.

    H1000 would be a much better choice than H4350 but here is what I came up with Quickload for H4350 and the 156gr EOL

    thanks, I talked to Berger Bullets this morning that they suggested to not even waste time trying to use H4350 in a PRC.
