I recently bought a "One Book/ One Caliber-Load book (9mm), as I can't afford all the manuals that are out there. I just started reloading 9mm & .40 S&W and wanted a light load using Accurate Powder #7, with Rainier 115gr. RN bullets (plated). Page 42-says to start with 6.6grs.- MAX,7.3/ I double checked this load online at accuratepowder.com, It's good thing I did, too! Their Load Data says 5.7 to start- MAX, 6.7 grs. NOW I'll have to double check all the loads in that book ! I tried 5.9 grs. to start w/ (#7). At the range-low recoil & flash,clean,all fed well in my Taurus 908- no problems!

I used to shoot Accurate No. 7 in 9 mm.

Using Lee's data, I tried 115 gr. Berry's over 5.7 gr. of AA7 at 1.140" OAL and the load was insufficient to cycle the gun. Using Accurate's load data, I used 7.0 gr. AA7 with an OAL of 1.145", and it still won't cycle. I increased the powder charge in steps to 7.6 gr., and I got reliable function.

Those failures could be related to a greater OAL than listed in the load (Accurate's data called for 1.130"), but I preferred to increase the charge (without exceeding max) instead of decreasing OAL.

I have a few of those "The Complete Reloading Manual for the (caliber)". Now I like them but I also double check the powder amounts due to mine where written in the 90's. Powders sometimes get changed such as Unique is a different powder now than it was etc. So if nothing else I would download the powder makers info listed on their sites to check it against.

I bought one of these and found the same kind of out of date information. I won't buy another I'd suggest buying one reloading manual for reference (I like the Lee manual but their load data can be out of date as well) and getting all your load data from the powder or bullet manufacturers' web sites as it will be the most up to date. And I've found you can email the manufacturers directly with a specific load question and they'll usually answer. I've even called them with postive results.

well buying all the manuals out there isn't reasonable and would become expensive.
but really depending on what projetcile that you are going to be shooting then go with that particular manual.
for example if you never intend to shoot barnes projectiles then it would be almost useless to buy a Barnes manual, speer pretty much devotes the loading data to speer projectiles , Hornady to Hornady projectiles, and if the particular projectile manufacture is also affilated with a powder manufacture many times only loading with those powders are listed.
so look for a broad manual that covers many different projectiles and powders, such as lee second edition/ Lyman manual, etc.
and of course all the powder manufactures have load manuals for free if you ask for one.
