Any Glock G40 10mm reloaders in here ?

[Chris2000ss]

Hello guys!

Picked up a Glock g40 MOS the other day and I'm waiting on my dies and Starline brass to come in that I ordered . Been reloading for several decades now but never reloaded 10mm. So In the mean time what is your favorite g40 10mm reload ? List load specs and velocity if possible and what you use the load for IE hunting etc ..

Chris2000ss, if you want to see some load info the tow places here on this forum are the 10mm load data collection
http://10mm-firearms.com/reloading-10mm-ammo/10mm-load-data-collection/

and Commercial Ammo Pull downs
http://10mm-firearms.com/factory-10mm-ammo-pull-downs/

There are many great loads to study in both areas, welcome to the forum and enjoy.

200 gr moly coated WFN with 13.2 grains of A#9 will do 1280 FPS out of a stock g40.

Replace the lead with a 200 gr. hornady XTP and it'll be around 1230 FPS.

The most velocity with hornady book data and the 200 gr bullets is with that powder.

Others here have attained more velocity with different powders by going over book max but that's not my cup of tea. Long shot is pretty popular for those endeavors.

Accurate load data shows a max load of AA#9 at 12.5 grains and 1170 fps from a 5" barrel with a Winchester large pistol primer and a 1.250" coal on a 200 grain bullet (XTP) (accurate_load_data_3.5.pdf pg 6).  They report this load has a pressure of 37,000 PSI.

Hodgdon load data shows a max load of 8.2 grains of Longshot producing 1172 fps, 5" barrel, WLP primer and a COAL of 1.260"  for a 200 grain FMJ. (http://www.hodgdonreloading.com/data/pistol).  They report this load at 35,000 PSI.

Reading between the lines of slightly different bullets (XTP vs FMJ), coal (1.250 vs 1.260) and pressure (37,000 vs 35,000) I would consider these two powders very comparable except for two factors.

1.  Longshot is going to be lots cheaper. AA#9 is a little more per pound..About $1 more right now at Grafs.  And you use 52% more #9 for the same result.  Works out to an additional $16.40/1000 rounds for #9 powder.

2.  You can't overload with #9.  Since it completely fills the case and is a compressed load, it isn't possible to load it beyond max.  To be honest, sometimes getting a bullet to stay seated over 12.5 grains is a challenge.  I have experienced COAL growing a bit over time.

Like MyAlias789, I stay with book loads.  I choose Longshot and Blue Dot over #9 more for economy than any other reason.

My favorite 10mm is still about 9 grains Longshot and a 180 grain JHP. Right in the middle of the road per Hodgdon

Really no complaints with the powders mentioned, AA#9, BD, Longshot.

But I use Longshot the most, by a, well longshot. Very pleased.

Congrats on the G40. I've had the pleasure od spending some range time with one. With and without a Gemtech suppressor. You've ordered the best brass that you can buy, in my opinion. My reloading experience is with its smaller sibling, the G20.

For max velocity loads, No. 9 for me. I've tried all the usual suspects with good success. No. 9 gives a lot of confidence because it seems to have a linear pressure curve, and, as Shadow said, it is nearly impossible to get enough into a case to break anything. Consistent groups, it meters like water, low flash and relatively clean.

It is inefficient, but powder is not a comparatively expensive part of the ammo.

For additional load data, look to Hornady or older Speer manuals.

I do like Long Shot, Blue Dot and No. 7 too for warm loads.

Ok so I couldn't wait for my brass to show up so I went  ahead and bought a box of federal American Eagle 180gr just to put some rounds through the g40. When picking up the empty brass I noticed that these were buldged . Is this normal even with crappy light loads ? I was able to resize them with my new lee carbide die and they look good

An even slight bulge around the base is normal at times... ( unsure of those rounds )
as long as you don't see a "glock smile" or bulge on one side

the even bulge with be removed in normal press die, glock smile brass should go in the trash

I haven't seen any smileys but there buldge is just on one side . I was able to remove it with my lee carbide die ..

Chris, the Glock barrels usually measure 0.4340" in the chamber and you will see that the brass can expand to fill the area.  So long as there is not a distinct line (aka SMILE) the brass should be reusable.  Understand that the reworking of the brass can make it "work harden" over time.  Pass Through sizing would be recommended to reach the areas not reached by standard sizing dies.
I utilize the LEE FCD die with the guts removed (aka bulge buster) to recondition all of my brass.  That has allowed my handloaded ammo to fit all of my various 10mm barrel chambers...

Thanks shadow. I did read your write up in the pass through sizing and I do have a lee factory carbide crimp die so I may start using that method..

That is a normal state for brass shot from Glocks. No issues. Reload them and shoot them. I have fed brass that has at least 20 reloads through them.

Here is an alternative opinion to consider:

I'm an outlier here in that I don't advocate pass through sizing as a matter of standard practice.

My recommendation is to locate a sizing die that sizes low enough on the case so that resized brass passes a case gauge. It will plunk into your Glock chamber with just about any die. In my case, I can shoot smoking hot ammo through my 40 bore Glocks. Both of my RCBS sizers make those cases drop right into my case gauges. I use a touch of Hornady One Shot.

I own a G-Rx die, but only use it very occasionally to clean up the rims that tend to get chewed up.

It isn't wrong to do it, but pass through sizing would add many tens of thousands of handle pulls for me over a lifetime (not to mention time spent), and my case gauges say I'm not gaining anything. Same with my targets. For progressive loaders, it basically doubles the number of handle pulls.

I have a G29 and Lone wolf G40 clone with their new slime frame.  On my G29 I have a bar-sto barrel.   I never felt safe shooting max loads in a glock stock barrel.
I thought it was standard practice to replace the glock stock barrel for a barrel with a tighter chamber.
But since no one mentioned it I could be wrong.

Not needed for the newer G20 and G40's.

I did run into a guy at the range with a fairly new G29 and he was shooting some factory loads. The brass looked really bad.
