    I have the most recent lee reloading Manuel, but the powder weights seem to be way off compared to most books. I've heard good things about the lyman book.

    I just want something with the recommended powder charges so i dont have to ask here for every powder or bullet i try.

    Thanks guys

    There is no such thing a "the most accurate" reloading manual.

    Manuals such as Lee and Lyman provide a smorgasbord of data on a variety of components. Manuals from the bullet manufacturers include only their bullets with a variety of powders. Manuals from powder manufacturers include only their powder with a variety of bullets. Imagine that!

    Lots of things affect what the manual authors find for their load data. The gun or test barrel, the atmospheric conditions, components used, and a pass through the lawyer's office can have profound affects on the data to name a few. There are others.

    Most reloaders have a a number of manuals from different sources.

    You will find that most data for similar components and the same cartridge really do not vary much between each one.

    Finally, you will need to work up the load in your firearm regardless what the manual says. Your firearm may react differently that the set up to develop the printed data.

    Not the answer you were looking for but i hope it helps.

    What makes you think what we tell you will be gospel?
    Get yourself a number of books--start out using the starter loads or close to them.
    Slowly work up you load--when you find an accurate load for that weapon--you have arrived.
    You don't need max load for every shot--they are hard on weapons.
    Have fun

    'Chuck' and I agree. Part of reloading is to "develop" a load for your bullet and powder in your gun using printed load data to do it safely.

    That's not the case for pistol loads. The published load data gives a range of "safe" loads for different powders and bullet weights & nose-types (FMJ, JHP, JFN, LRN etc.). If you find load data for a powder that has a fairly "wide" range of loads, it gives you a bigger safety margin for load development. If you use the same bullet weight AND type/nose shape bullet and start at the low end of the data, you can safely test your new bullet and work up to the load you prefer.

    For your pistols, 9mm loads are the most sensitive to smaller changes because of the small case volume. Compare Win 231/HP-38 to say Vihtavuori 320 load ranges as an example. The Win231 (same as HP-38) has a wider load range for each bullet published than Vit n320 or 310. The Win 231 is more 'forgiving'/less sensitive to small changes. Win 231/HP-38 is used for 9mm and 45ACP by many.

    Hope this makes sense..

    I Agree There is No Most Accurate book.

    I Have:

    Sierra
    Nosler
    Lyman
    Lee
    Hornady
    Thompson Contender (kinda Specialty manual)

    Anyway I use them all and work loads between all of them. The Bigger the Library, the better! I love them all.

    I think they each have some of my favorite loads or info in them!

    Yes every book will be "most accurate" for the firearm/complainants/conditions when worked up. Now you CAN"T duplicate the exact same conditions. The info is meant as a safe guideline for you to consider as a max load. I would not consider less than 3 sources for each loading before I attempt to load my own and use them all to form my own opinion about a safe load. There are on line manuals so you don't have to buy them for the major powder and some bullet manufacturers that can help you reload safely.

    I use Hodgdon's powder and find thier data to be the most accurate. For example, Lyman gives a charge range of 3.3-4.9gr of 231 with a 115gr FMJ, while Hodgdon says to start at 4.7gr. My XD doesn't reliably cycle until I use 4.5 or more.

    They are a little different. I use:
    Lee
    Hornady
    Lyman
    I think they all have their place. One of the most important reloading books I have now though is:
    Bubbacrabb's reloading manual for bubbacrabb's guns.
    I keep this journal going with notes on what I liked, what I didnt like and the best load i've found that I liked the best in the variety of weapons I shoot. I tend to open that thing up more than I do any of the others. You just need to start loading and figure it out, start low work up.

    I use my bullet manufacturer books, powder manufacturer books, and the One Cartridge/One book. It's so nice to have multiple refrences, doing so helps eliminate loading issues quicker, and also provides various perspectives for me to utilize.

    The most accurate loading manual is the one in front of you when you start loading. Otherwise there is no such thing.

    The one you make yourself from meticulous testing with different loads for a particular rifle

    Everything else is just an educated guess but still good general information.

    There are indeed differences between loading books. But, we can be sure that no book maker provides foolish data so there is no stand out that's better than others. Sorry, it would be nice, but there is no such book, they are simply guides to get us started and set a reasonable stop point.

    IF all the book makers used the same test firearms and bullets, powder and primer lots and cases they would likely present very much the same data. Our rigs and components are different from theirs. Therefore, the book variations should give us a clue that our rigs can't be expected to mathatically duplicate any one manual. WE have to make sure we know what WE are doing because only WE can make sure what we load is safe for US.

    Read and weap...Comments 1 through 6 are the answers you were looking for. There is no "most accurate" loading data manual. That's why it behoves you to have at least 3 (or more) loading data manuals to compare to and pick a starting load and work up. I nor anyone else on here can give you a load that will short cut the process. Soooo...Sit down at your loading bench and get busy learning what we already know.

    I use a Lyman and a Speer. Often there is a big difference in what amount they specify. That is why I check with my reloading guru and powder web sites also. Way too much excitement going on next to my nose to take chances.

    I use the Lyman #49, Hornady #6, Speer #14, and Accurate #2 manuals (and several older ones kept for reference). In my experience, the Speer manual usually provides chronographed results closer to what the book says than the others. YMMV

    All manuals are as accurate as far as the lawyers allow them to be!

    So im going to start by ordering

    1."Lyman "Reloading Handbook: 49th Edition" Reloading Manual Hardcover"
    2."Sierra "5th Edition Rifle and Pistol Manual of Reloading Data" Reloading Manual"

    They're both rated 5 stars on midway.

    What do you guys think about those two, plus my lee modern reloading manuel i have now. Any other recommendations?

    I just threw "Speer 11" at my wife's cat, and got a direct hit.

    You didn't mention, but shall we presume you want to reload 9mm, .45ACP and .223?

    If so you have more than sufficient tested data to proceed with all the manuals you mention. Probably much more data than you will ever use.

    All manuals do is compile data showing exactly what they tested and what results they achieved with a given set of components and testing equipment. Some do their own in-house testing others, like Lee, compile data results from others.

    You also will get good load data from the various powder or bullet manufacturers' websites. For example, I use Hodgdon powder and visit their reloading database at:

    The most precise data usually comes from bullet makers' manuals, because they had more time to focus on a much smaller selection of bullets. Ditto with powder maker's manuals, though not always.

    But the best bet in general is to have a lot of manuals and to compare the listed data, then work up your loads to see what is the most accurate. Lee's manual and the loadbooks are usually where I start, but I may end up consulting four or five books plus back issues of handloader. The firearm itself creates all sorts of variables that no manual can predict, so you have to craft many loads and fire for effect to find the best.

    Or insurance companies, which would be close to the same thing.

    Also, as has already been mentioned, every load that someone recommends, especially on the internet, should be checked by a manual or the powder companies website.
    I have loaded loads that were recommended here on THR many times, but I have always double checked them to make sure they were within safe limits first.

    +1 on the notion of triple checking ALL data you read. Like a newsman once quipped, if your mother tells you it's raining outside? Check it out first before reporting it.

    As your thread topic demonstrates (manuel vs manual) it is far too easy for spelling errors and typos with numbers to appear on the 'net. Even long time posters can create an error without realizing it. Check and verify, especially with things that go bang.

    I haven't used the bubbacrabb's yet but I have one like it called kingmts loads.

    Most of what I load there is no or very little data for it. If I don't know a powder I look for data that has close to the same burn rate & use the data for that to get an idea of what I'm doing.

    I think that choice of a projectile is entirely too heavy for cats. You would be better off using one of the Loadbooks pamphlets for varmints such as cats.

    Speer 11 was plenty accurate, but now the varmint has been shot over, I may need a faster projectile.
