    Hello,

    This is the only published load data I've been able to find for the 8x56r. The one manual I think might have it in there is missing. I brought it home and I suspect my kids got it or my wife "put it away."

    Whichever, I have limited experience with H4350, having used it only for heavier bullets in the 7.62x54r. I have no experience with IMR4350 or ACC4350. How similar are all these to each other?
    The bullets I have are around 208gr and I have H4350. I found near 1,000 primers I forgot I had, and they are large rifle CCI magnums.

    Given these components, would you use the 220gr H4350 starting load under the 208gr bullets I have? What effect would this have on the H4350 powder, if any?

    Thanks!

    Josh

    The only load I have that you do not is
    206 ball IMR 3031 45.0 gr for 2300 fps military load from 12 th edition Cartridges of the world.
    That is a lot hotter than your Lee data.
    You should be fine with 220 gr data using 208 gr bullets

    Dang, my books are buried. When I load H4895 and IMR4895, though close, there is a difference.

    I always play it safe with new loads. Load up a few and chrono them if you have the ability to easily. I would start at the 220gr load personally, but like I said, I always play it safe.

    The 8x56R is a known shoulder beater, particularly because the M95 carbine is a little on the light side.

    I would suggest pug loading it down on purpose, unless you like a lot of recoil.
