9mm OAL and bullet question

[m-man]

So i've been only reloading .40 for a while, and i am also starting 9mm,
I made my first one and i noticed that the bullet only goes into the case a small amount, compared to what i'm used to with .40 where the majority of the bullet goes into the case.
I am at the OAL that is recommened from the Hodgdon website of 1.150"
it looks like less than half the 'base' of the bullet in in the case,
Is this normal?

If you can, take a look in the bullet mfr's load manual (Speer, Hornady, Sierra, etc.) particularly for HPs or TCs. Not sure what weight your bullet is (124?) but the loads in an old Speer manual that I have show 1.120 for 124 gr HP's and as only 1.050 for 100gr HP's.

Your bullet prolly won’t chamber at that oal. TC bullets need to be somewhere from 1.050” to 1.200” depending on the chamber in your pistol. Look at Hornady data as they have a lot of TC bullets.

This linked site shows min and max OAL (and other related measurements) for various 9mm loadings.

Are those bullets Berry's 115 grain Flat Point? I experimented with those and read that Berry's recommends 1.05-1.08". I seated them to 1.05" and the rounds still don't reliably pass a bullet drop test in short throat barreled guns like CZs or 9mm Kimbers.

Err with caution and start your loadings low. At 1.05", the entire bullet will be seated lower in the case than a round nose bullet at 1.125".

In my experience with loading 9mm the throat depth seems to vary more than any other caliber. I've probable loaded over 50K 9mm with many bullet types. I pretty much use dummy rounds and the plunk test on my shortest throat barrels [CZ and Tanfo] to determine OAL. Books will say 1.150 and the best I can get is 1.115ish. Some bullets like Montana Hold 124gr HPs I can only load out to 1.080. I just start with a mid range load work my way up and watch for pressure while chrono-ing my loads.

I would do a "plunk" test with that bullet. Load it till you can plunk it into the chamber of the barrel and turn it freely.
