Ignorant and curious minds want to know...
Reloading manuals answer these sorts of questions and are the resource most valuable to the reloader. If you don't have one, pick one up and if you have one, pick up another.
Another good option is to check the Lyman manual. It typically has several different bullet weights/profiles listed for each cartridge, along with appropriate cartridge OAL for each.
(I don't have a reloading manual...shh)
But I was able to magically use the internet and find out that 1.169COAL is the maximum COAL for the 9mm. Probably not a good idea to attempt to load to that length unless you are measuring each one by hand. It's common to get a little variation while loading and if you shoot for the maximum you could end up past. Find a reasonable COAL that works for you and try it out.
I don't know how else to put this JD, so I'll just come right out and say it: Comments like this are EXACTLY why you need a reloading manual. I could sit here and type it all out for you, but the simple fact is that you are ignorant of what the cartridge OAL number is there for, and it is NOT the absolute longest you can load to and stay safe.
With all due respect...go get yourself a book and read the dang thing. Heck, TAKE A CLASS, if that works better for you. Whatever you do, stop giving reloading advice in a public forum. You don't know what you're talking about. I don't say that to be a d**k, but to alert others reading this stuff to take what you're writing with a big ol' grain of salt.
Compared to rifle cartridges, seating depth in pistol rounds is critical. In another thread, posted earlier today, you explain that you're going to go back and re-seat 1,000 cases for OAL. The weird thing is, you don't state that you're going to CHECK THEM...just run 'em all through the machine again.
JD, here's what I'll tell ya. You're wrong on a few important, and fundamental, aspects of reloading. You do not understand the association between cartridge OAL and attendant pressure. You speak of loading to less than the recommended length as though it is a safety measure, when the greater concern, with respect to high-pressure pistol rounds, is loading TOO SHORT!
The accepted convention for seating bullets in pistol cartridges is to follow the recommendations in the reloading manual. Compared to rifle cartridges, seating depth in pistol rounds is critical. In another thread, posted earlier today, you explain that you're going to go back and re-seat 1,000 cases for OAL. The weird thing is, you don't state that you're going to CHECK THEM...just run 'em all through the machine again. The notion of someone owning and operating a progressive press, but not owning a reloading manual, is..."unwise". That's probably the nicest term I can use.
If I have called you any names, I apologize. Based on what I've read, you should NOT be giving anyone tips on reloading; I stand by that, until you prove otherwise. I'm guessing you've been reloading for a year, if that, and you think you've got the tiger by the tail. The thing is, the smartest people I know are deserving of that respect largely because they are very careful to not imply that they know something, when they don't. You have an awful lot to learn about reloading, and if you ever get there, you'll look back on this little discourse and think, "Man...he was RIGHT and I shoulda kept my mouth shut!" That's not an indictment, just a little snow on the rooftop talkin'.
Honestly, I wouldn't call anyone ignorant for looking up the information on a credited site such as hodgdon.com instead of in a reloading manual. I don't own a single reloading manual and I do just fine. The reason I don't own a manual is because out of the 3 I've looked at all of the information varies.
The manual that you own I'm sure lists a minimum and a maximum OAL for each round, just as every other manual, but I'm willing to bet that if you look in multiple manuals you'll find that the minimum and maximum are near each other but not exactly the same.
JD has just as much right to post his opinions and experiences on here just as much as you do, sir. Nobody on here (including myself) can prove that they know everything. It's simple knowledge. As far as taking everything he says with a grain of salt, I'd take everything you see on the internet as well as a reloading manual with a grain of salt. While manuals are books written with someones experiences, this forum as well as other reloading sites are the same thing only in virtual form instead of in a physical book that you can hold. Who's to say they didn't mis-type the information in that manual?
Just my about getting frustrated at people because they would rather look up the information on a website than pay $30.00 for a book...
You say looking up load recipes on Hodgdon's website is a perfectly fine way to determine what loading components to use. I tend to agree. Please post a link to the portion of Hodgdon's website that teaches you HOW to reload safely and effectively.
Hodgdon is a marketer of powder. They do not manufacture powder. They buy it from suppliers, marketing and selling it, wholesale.
As such, there are some questions about where Hodgdon gets their data.
Have you ever seen an actual Hodgdon reloading manual, per se? No, I'm not talking about the 72-page advertising and load recipe PDF you can download from their site. I'm talking about a real, honest-to-goodness, hard-cover, tome of information that you can refer to over and over, like a trusted friend.
Let me ask the question another way: When you have a choice of load data from a powder company or the bullet manufacturer, whose do you go with, and why?
You say the loads in the books you've looked at vary. Did you notice what EXACT components they used, or what rifles they were fired from? If you owned those three books and someone bought you a 270 Weatherby for Christmas, you could look through each of them and get different perspectives on what loads to test.
Instead, you're just going to go out to "loademifyagotem.com" and hope for the best?
I guess if you reload for a couple pistols and 223, maybe a reloading manual isn't "necessary", but I do have to ask...how did you learn what process to follow, and why? Did you learn everything you need to know about reloading from a friend or two and the Internet? I can't even fathom why someone would intentionally handicap themselves like that, particularly with something that is potentially dangerous.
OF COURSE cartridge OAL is not the same for every round! Why do you think it would be? The shape of each bullet isn't the same, is it? So, how could the recommended OAL always be the same?
If nothing else, you have different bullet weights to contend with, so naturally you've got different lengths. This is the kind of "Reloading 101" you'd know if you actually read a book or two on how it all works.
JD has a right to express his opinion, but I have a right to point out the gaps in his knowledge base.
Some might say experienced reloaders have an obligation to do so, to protect unsuspecting readers from bad info!
Now you say to take everything on the Internet with a grain of salt. Does that apply to Hodgdon's load recipes??
No, this forum is NOT the same as a reloading manual! Do you have pressure trace equipment or a universal receiver, with a SAAMI spec barrel and proof loads for testing new components? Do you have any way of verifying the loads mentioned on this site are safe?
If I tell you about the loads I use in my 44/40 Model 92 Winchester, do you know whether or not those are safe in your 1880's revolver?
Reloading manuals are documented and proof-read and gone through with a fine-toothed comb by editors and lawyers to make darn sure that if a gun blows up, it's YOUR fault. Not so with a single thing you read on the internet. Go ahead and search for a load on Hodgdon's site...the first thing they have you do is click on a disclaimer that basically says you'd better know what the heck yer doing before you start reading.
Sorry, but this is apples n' oranges. Someone who reloads ammunition should have a reloading manual, or 5. If you don't, and your efforts are narrow in scope, you will probably not blow yourself up. For most people, who like to be well-informed and load more than just 223 and 9mm, load books are something they trust and take comfort in. Read one...no, really READ ONE...and you just might learn a few things ya didn't know.
