Question Cartridge Overall Length - Missouri Bullet 9mm 125 Gr.

I am just starting to load this bullet, and am puzzling over the overall length. My manuals show quite a variation for 125 gr lead round nose bullets.
Has anyone used these, and settled on a satisfactory overall length?

Yes, I use a gazillion of them.

What gun are you shooting them out of?

Because the have a very rounded profile, I need to seat them very short to chamber in my CZ and Browning HP, so it's important to seat them to what barrel you have.

One length does not fit all, you need to take out your barrel and do the drop in and out test. Let me know .

I loaded up a small batch with COL of 1.130. The Speer manual shows that for their bullet.
I want the load for practice in both a M&P9, and a Ruger SR9c.
Shot 10 rounds in each pistol this AM, and functioning was perfect.
Do you see any reason to change that COL?

Speer #14 does not list that OAL for their bullet. They do not list a 125gr lead bullet??. They list 1.135 for their 124 gr TMJ bullet which is not the same shape as the MBC bullet.

You are in the ball park. My Lyman manual shows a lead bullet similar and they load it a bit shorter at 1.065.

What powder are you using?

They are probably fine, as you stated they worked. The best way is to load some dummy rounds a little long seat them and taper crimp them. Then drop them in the barrel, they will probably be too long. seat them a little bit more and keep doing this until they drop in with a plunk and drop out when you turn the barrel upside down.

I am sending you a PM with a link to another web site which has great pictures better than I can explain it.

Thanks for the link.
My Speer manual is #12, and shows the COL for their bullet part # 4601. It is a 125 grain L-RN.
They must have left it out of the newer manual?
Thanks again.

OK, as long as the shape is similar and has the real rounded nose like the MBC you should be good to go. Just remember there is no set OAL unless it is the exact specific bullet that is used in the testing. So you will see all kinds of OAL. The link I sent you will take a lot of the headache out of finding the right length. Also, if you go shorter, pressure increases so do not be using Max loads and then use a shorter OAL.

What powder are you using??

I have a lot of Bullseye, so I thought I would start with that. I am loading 3.6 grains.

The variation of OAL for 9mm is huge. And combine that with the pressure changes due to increase/lengthen versus what the load was developed with makes life challenging.

The best way to deal with this is to focus on "bullet seating depth". While this isn't list in current reloading manuals, it is easy to determine. Case length + bullet length - cartridge OAL = bullet seating depth.

If you don't happen to have the bullet length of the bullet used in the load listed in the manual, most are available here:

If it ain't broke don't fix it.

Sometimes we get lucky and find a good load the first time out. as long as that ammo is accurate I would leave it alone.
