Recipe for 9MM Please

[Hogxtz]

I only have experience with .40 and 556. Today I looked up specs for 9MM as I put a Wolf conversion barrel in my G23 so I can shoot 9mm.

I am very confused about the COL. With Extreme 9mm 124 FP, at 1.140 it seems the base of the bullet is barely inside the case, much different than the .40 I make. I called Extreme and they told me 1.140 also

It seems so shallow that I kept checking and zeroing my mic because it doesn't seem right. A very long portion of the bullets shank is sticking out. I would be afraid to use these unless they were crimped by king kong. Is it just me? Is this how 9mm seats?

So anyways, I was hoping somebody could recommend a starting load and double check the COL for me.

Ammo for G23 with Wolf conversion barrel
Range brass
cci small pistol primer
Xtreme 124 gr flat point
Winchester 231 powder.

Thanks in advance

I think the COAL of 1.14 is for round nose. A quick seach shows 1.05 for the flat point. Don't quote me on it though, I'm at work and don't have access to my manual

I do not use the powders you mentioned, but I load both Xtreme 115gr and 124gr round nose to 1.1" even.

Have you measured the bullet size and weight? Just asking.

1.140" is what I used for Xtreme RN, when I switch to RMR FP and want to maintain the same internal case volume, I load to 1.117"

Yes I did weigh them and measure the diam. I was wondering if maybe they were boxed wrong but they are good. I have been searching the internet and I am beginning to realize I have yet much more to learn about reloading. It appears this question has come up several times before for 9MM. I read that some guys seat the bullet just enough to clear the lands of their given barrel, that the seating depth isn't that critical above 1.10 as long as the powder is kept in the low to mid range.

Oh and I called my two local shops for obtaining a recently updated reloading manual and everybody is sold out? WTH?

I load my 124gn at 1.08 coal with 4.8 gn of cfe pistol. It works for me.

Take the barrel out and drop in a fired case into the chamber and see how it looks then drop in your loaded case and you will be able to tell if the bullet is not seated deep enough.

There are a lot of factors which will determine the OAL of your 9mm load in your gun
The maximun OAL is 1.170", but I've never seen anyone load this long

First the OAL has to fit in you barrel/chamber, then it has to fit in you magazine.

Loading Xtreme 124 FP I've found 1.060" to be common and works fairly well in my case for my CZ but we know how short the chamber can be on those. Give me a second and I'll get back to you on where I got my 231 load.

[Joezamboni]

I'll suggest you look at the Hodgon online reloading manual and check the load values for 124g and 125g seated at about the same depth. I used 4.0g without issue or any signs of excess pressure on the brass however due to the lack of data didn't feel comfortable pushing it much higher with the short COL. No chrono so can't guarantee its a safe load.

This. Plunk test. Works great.

For a berry's 124 flat point, I ran 1.045" coal, but I don't remember if that was before I had the barsto barrel finish and taper reamed. After the gunsmith first fit it to my XD 40 pistol, it had a very tight chamber and required a very short coal.

For plated and moly coated bullets I usually run 4.0 grains of hp-38 or win 231. In my AR 15 9mm, I found that 4.2 was a little better and it runs fine in my pistol but has a tad more recoil than my favorite 4.0 pistol load.

Titegroup is what I run in my 40 right now, but it is very fast and it takes very little powder for a light load. It doesn't even fill the case half way and is hard to see as it comes around the 1050 plate to get a bullet from the bullet feeder. Seating by hand, one station closer to me, lets me check the powder easier but I like the feeder. After about 2 decades of reloading, I still am not crazy about tightgroup for light loads because of the density.

The plunk test is the way to go. Also, don't use more crimp than you need. On a plated or moly bullet, it deforms the bullet and causes standard deviation numbers on a chrono to increase and it can hurt accuracy. It is easiest to use an individual seating die and then crimp die. Load long as long as it feeds reliably and fits and feeds in your mags.

Red dot powder is good for pistol and is a bit more forgiving than titegroup, with similar feel for recoil and a fairly quick burn rate. 231 is a favorite of mine though.

Your numbers was for a RN.
