    H-322 & Hornady 55gr FMJ

    I need a bit of advice..I'm wanting to load the above, But the newer hornady manual shows 23.1 as max..(using a Rem700 and a 26"bbl)A older loadbook that has a section for AR-15 loads(using a Colt with a 20"bbl 1/7 twist) shows h-322 going up to.. 24.3 as max..I know you can go a little hotter than 23.1.. I was thinking of using 23.3gr, as I've done a search and read a few other people using it with good results in their AR's. This would be used in a AR with a 5.56 chamber (DD barrel) Has anyone use 23.3? Results?

    Hodgdons shows 23.1gr as max for a Speer 55gr SP.
    Work it up and check for signs of pressure.

    Markm works with h322 a lot. Maybe he has some info, most of what I have seen he loads 77 smk with this powder though.

    I've loaded 55gr to Markm's 77gr load wich is 21.6 grns with no issues in my DD. Smooth load but cycles fine.

    Man... It's almost a crime to load that good powder with 55 grain bullets... but if that's all you have in the current market...

    I've never tried it with many light bullets. 69s and 77s love it though.

    I know what you mean. I had a guilt trip myself loading them. H322 was the only powder I could find at the moment so bought 6# worth and got to it. Btw that 77gr load groups very well thanks.

    There's no price difference... but it's still a bummer.
