9mm (9x19) What to do, Could use input.

[Nevada Ed]

Let's go straight to the manufacturer. Hornady lists the OAL for the 115gr XTP at 1.075". They do not list N320, however.

I can also do the 1.075" OAL with the Berry 124 gr. THP bullet, but

with any other bullets that I have, I need at least a longer 1.10"
just to get average accuracy with the little 115 gr's and at least
1.12" with the Speer Gold Dot JHP bullets, and all the heavier bullets, that I load.

This....
The Plunk Test - Setting your OAL - 9mm/38 Caliber - Brian Enos's Forums... Maku mozo!

That article advises shortening your OAL by .05" after you get it to plunk and spin.

That seems a bit excessive, and possibly dangerous.

I think he meant .005".

I just shorten a loading until it chambers (and extracts easily without firing) and call it good.

From my experiences, I don't think the 1.142 COL is your problem with this one. It's well under the max for 9x19, and among my favorite loads, I have one that is 115gr FMJ at 1.140.

One thing I do remember from when I first started reloading is having issues getting the crimp and bullet depth of the dies setup correctly. There were times when I didn't have the die down far enough to completely take out the flare from the charging die, and other were I had things set too deep and distorted the case, in both cases the round would not chamber correctly, although the length was within spec.

Getting back to the original question on this, I would pull the bullets, take the decapping pin out of the sizing die, and start over, using a cartridge gauge or plunk test the first few rounds until you are confident things are setup right.

I have a similar problem, turns out that 70 cases are too long to chamber in my Lymann chamber checker. After separating out all the problem cases the reloading went fine with the others. I will eventuly take my 9 EZ apart and see if they chamber in the barrel, if not then try to rig up a cutter so I don't have to de-prime the cases, hate having to risk mucking up 70 small pistol primers if I don't have to.

I've decapped quite a number of primed cases over the years. I haven't had one pop yet.

I ran into the same problem a few years ago when I changed bullet style but forgot to recheck my powder load. After 200 rounds I figured it out.

I pulled all those bullets with a collett bullet puller and reused brass and bullets with the proper load.

I felt much safer doing it this way.

You might try seating those primers, one more time with a little more pressure on the unit
before you start trimming all those cases.

Good luck.

As for your OAL

A LOT of this depends on the pistol being used.

I have one 3" where a 124 FMJ plated "Ball type" bullet will work at 1.09"
A C9 3.5" where a Berry 124 THP at just 1.075" gives me great accuracy and high FPS.
I also have a full 5" that can "Plunk" a 124 FMJ set at a long OAL of 1.22"
but that setting, will not fit in the magazine.

When working with a new bullet, a "Dummy round" will save a lot of future problems for each gun it is used in
or at least take measurements and log them.

Good Post !
Keep those dummy's around...they come in really handy the next time you want to adjust your Seating / Crimp Die .
And are a good way to use a berdan primed or other un-reloadable type case ...
For the new guy's ... a dummy round has no primer or powder just a bullet seated and crimped in the right spot.
