Title: Is Anyone Loading Their Own 10MM??
Post by: actionshooter on July 30, 2021, 09:57:22 PM
 I am thinking about loading my own HOT 10mm for my Glock 20 instead of buying the high end defense loads... similar to Buffalo Bore... Is anyone doing that? What is your load/ experiences doing this?
This would be for backing for 4 and 2 legged varmints in the west and Alaska.

Thanks!

Yes!

I had some Underwood ammo I broke down to see whatís in it and was able to replicate it without having pressure signs


Using 200gr xtps and pushing them at 1250+


Running them in a stock g40

This is a website with TONS of data
But as with any reloading itís at your own risk.

Silhouette powder max
180gr bullets
Glock 29

Peppy enough to feel like Buffalo Bore.

I just bought a Glock 20, since ammo is still hard to find I loaded my own.  Starting out in mid range with my gun new and all.  With my barrel out of the frame I dropped a loaded bullet into the chamber only to find it rattling around in there.  I grabbed my Glock 19 and tried a 9mm round in it and it was snug.  So the I grabbed the ball gages and my micrometer, my chamber is .013" bigger then my round.  So my brass would be stretching each time I loaded the case then shot it.  Plus Glock will tell you not to shoot lead bullets out of their stock barrel.  With these two factors I ordered an aftermarket barrel for mine then will be shooting my reloaded brass out of it.  Dreadi maybe you can give some input on what I mentioned?

I've had great luck with Longshot, loaded with 180gr xtp's.   If you look at ballistic gel tests, the 180's and 200's had about identical penetration, with 180's shooting a little flatter.   

I have also heard Blue dot, and 800X powder work great.

Shooting reloads will void your warranty. Lead bullets are fine in Gen 5 Glock pistols.

Also, look at page 30 https://saami.org/wp-content/uploads/2019/02/ANSI-SAAMI-Z299.3-CFP-and-R-Approved-2015-12-14-Posting-Copy.pdf

And compare your chamber and rounds.

i've been wanting to load my own "hot" ammo for my glock 29.  i bought it during the early days of covid when factory ammo was still "mostly" available, but by the time i got around to thinking about loading for it, dies and brass had completely dried up.  not necessarily planning on doing it to reuse brass, but more because there doesn't ever seem to be much heavy 10mm available locally, and you seem to have to pay dearly for it.  my glock seems to spit empties way out into the weeds so i feel lucky if i recover 1/3 of my brass anyhow.

i had heard blue dot is the ticket for heavy cast loads.  i'm not concerned about leading, as i put a kkm barrel in my pistol.

When you crimp, you want to take out the bell just enough for the round to slip into the glock chamber and it should be a bit loose, you don't want it tight.  You don't need an aftermarket barrel but if it makes you feel better, just use coated lead bullets with the hi-tek type coating.

Buy a .40/10mm Lee FCD. It puts a perfect taper crimp on your cases and also resizes the entire body of the case again to ensure it will fit easily into your chamber. Excellent investment. I have them for all of my auto loading pistol cartridges and Iíve never had a malfunction.

I like the 200gr bullet from Montana Bullet Works over Alliant 2400. I've shot this combo in a few different 10mm pistols with good results. Start at 9.5gr and work up until the gun tells you to stop. I'm at 1275fps with 11.5gr of 2400 in a 5" Kimber with a 22# variable weight recoil spring, 28# hammer spring, and a flat-bottom firing pin stop. I don't know if I'd go that high in a Glock or other stock pistol though.

I am looking at those... probably will be the way I go but have you ever tried the 220s? I have not been able to figure out who is making them.

I played with the Cast Performance 220gr in both of my 10ís and wasnít happy with them. They never penetrated in a straight line, always veering off course a couple inches into whatever I was shooting. The 220s are ridiculously long and I donít think most guns are properly stabilizing them. I think I have a couple hundred of the 220 on my shelf if you want to try some.

For comparison, these are unfired and recovered bullets shot into 20% gel blocks. Thatís a 200gr from Montana Bullet Works, a 152gr bullet I had Hammer make for me, the Cast Performance 220gr and a 180gr XTP.

OK, starting the load testing and am going to use Longshot (only powder I could find), 200gr Montana Hardcast, Starline Brass and winchester primers.... Has anyone used the Longshot for a similar load?   I'll post results soon.
BTW.... this will be in a G20
