    .223Rem loads with H870 or AA8700?

    Anybody ever put together some reloads with either of these powders? Looking at some of the pull down powder from Bartlett's Reloading is the reason i ask. 55grain FMJ plinking rounds on the cheap is my goal. Thanks

    Well, that is way to slow of a powder to use. Well, you need to read up on powders and burn rates!

    well aware that those two powders are some of the slowest around but it never hurts to ask.

    You're right, it never hurts to ask. The only stupid question is the one not asked. That said, way to slow.

    And, not only that, it's way too slow, too...

    Raises a good question, tho. I am a reloading noob, too. What are some general rules of M1 thumb when considering burn rates of powders for various calibers?

    A good loading manual or three is probably the best place to look to find what powders work in which cartridges. It depends on a cartridge's case capacity, bullet weight, what is wanted from the load, and more. For instance in the .223 with light varmint weight bullets can use powders like Benchmark, H322, AA 2015 and 2230, X-Terminator, and the like. For heavier bullets for high power match shooting powders like H4895, Varget, Reloder 15, and the like are used.

    870 and other similar surplus powders are cannon powders (really!), and meant for use in large capacity magnum rifle cases.

    Invest in hard cover reloading manuals. Most indicate what was the most accuracte powder for the most part. One has to pay particular attention to the components used in reloading manuals and for the New reloader folllow them to the letter.

    Investing yourself will answer a lot questions. And, if you check the powder mfg web sites, if they do not list powders for specific carts it is not viable, for the most part.

    Get a copy of the Lyman 49th, and The ABC's of Reloading great resources. Investing in yourself is paramount to reloading success!

    Always good reading material when using the throne!

    You know that's impossible right. Load data can NOT be followed to the letter. To do so one would need the Exact same components, exact same lot numbers, exact same temperatures, exact same weather conditions, etc.etc. Not to mention the EXACT same firearm or test barrel used to do the testing. Not one just like it the exact same one. Changing brands of primers or brass is nothing compared to a completely different firearm.

    Published load data is not a recipe and should not be treated as such. This is one reason why we must always start low and work up.

    If you're a newbie, stick to published load data from established powder and bullet makers and avoid surplus powders until you've got some reloading experience.

    I didn't see it mentioned but even if you wanted to use it, you couldn't. H-870 has been discontinued (several years ago) and is no longer available. AA-8700 can still be found here and there, but it's scarce as well.

    The pull down powder in question uses data from either H870 or 8700 but it's way to slow as everyone pointed out. Real shame considering you can pick up 16 pounds for the same price of 8 pounds of H335
