    I was wondering if anyone had load data allowing H4895 to be used with a 123gr. FMJ. I am not 100% sure if the two can be used together. I have found data using a 125gr. bullet, just not 123gr.

    I would recommend getting a couple reloading manuals.
    And the H4895 will work for 7.62x39 just fine

    I have a few referance manuals and they all show little info for 123gr. Most of the info I have calls for IMR 4198 and a few other powders. I currently have H4895 and thats why I am trying to find info on it. If I have to get another powder, so be it. I figure if I can use what i have, even better. As long as it is safe! Thanks.

    The main reason I do use IMR4198 although I do have H4895 on hand. The IMR4198 seems to be highly usable across the entire board of bullet diameters, weights and types. It's just such a well rounded powder for this, err, round. :)

    It is strange that: A look in my Loadbooks manual shows the use of H4895 twice w/ .311dia 125gr SPs & .310dia 150gr SP bullets and nothing else. IMR4895 only shows one use with a different .311dia 125gr SP.

    But: When it comes to using the .308dia bullets and 4198 powder, both H4198 and IMR4198 are shown being used on all weights and bullet types from 110gr through 150gr.

    You could do as others have indicated in just using the load info for the 125gr SP bullets and maybe back off 10% to start out with... but just another thought, you didn't say what diameter bullets you were using. Another item that'll influence pressure.

    The round is .310 diameter. I think I am going to continue to do a little more research to find the proper load. I am not in my opinion experianced enough to start experimenting. It probably would be wise to just get the powder that is called for. I thank you all for sharing your wisdom to a rookie.

    Looking here @ Hodgdon Data:

    122-125 gr
    .311 dia.
    H4895 start 28.0gr. MAX. 29.0gr.

    H-4895 is on the slow end of the burn chart for the 7.62x39. Notice Hodgdon data---29gr Max at a measly 2249fps and very low pressure 33,600 CUP. That's because that's all the powder that will fit into the case, 29gr of H4895 comes right to the top and is heavily compressed. Don't get me wrong, I like compressed loads, but I also like them to give me better performance that H-4895 does in the 7.62x39. It will work, but there are better choices out there.

    I have a Ruger Mini-30 with a .308 Diameter bore, I have tested just about evey powder you can think of in the 7.62x39. AA 1680 was developed for the 7.62x39, it works and is favored by many. I shoot a lot of it and it produced OK accuracy and good velocities with 123-125gr bullets. That said I like other powders better, for accuracy and velocity I like H322, N-130, H-4198, AA 2015 and R-7 in that order.
