10mm historical load research

[preventec47]

.it appears one manual you did not have access to was the Hornady. One of the top loads they have listed for the 155gr-XTP was 15.1gr of AA #7 max at 1450 FPS from a 5" barrel.
.

CTK-
Could you please verify your manual version and data for the AA#7 with 155gr XTP bullet. Since my post on 10Talk I have received some info
fm Hornady manuals.
I dont have the actual manuals but the info reported to me in
my research is as follows:

> 155 XTP  13.9gr AA#7 1400 fps  Hornady 4th edition
> 155 XTP 14.6 AA#7 1455fps Hornady 7th edition ? ? ?

Your data shows .5 gr more than the other info I have received
from Hornady manuals and is very helpful.


I have ordered the a summary manual which was published in yr 2000
and am hoping there will be some older and higher performing
loads. see the attached image

After you verify, I will update and post my summary of the best loads found to date for 10mm

Thanks Much
Scott

Hornady data

Preventec47, I have some of the early data sheets for the 10MM and forty in a pdf.
I can attach it to an email and send it along to you so you can compare the data.
Feel free to share or post the info.

The 10MM data is from Hornady.

BTW There are 3 pages of 10mm data and 4 pages for the 40cal.
This data seems to compare with what is currently published but predates loading manual data.

PM me your email if you want the data.

i dont reload, no room for it and dont have the $$$ for start up costs anyway.

so you can see why im disappointed in DT's fall from grace.

i prefer the DT 135gr. Nosler h.p. for my G20 and G29.

i do this because DT claims 1600 f.p.s. for this load from a stock G20 bbl, but i know im getting a bit less than that i dont want to go heavier and have escentially .40cal "+p" loads because they fail to live up to the box flap velocities.

BB makes a true 10mm velocity round but the lightest they have is 180 grain bullets and $1.50 each.

CB makes what DT has become, which is a mid powered 10mm loading.

Win STHP never was full powered because they never got the 1290 f.p.s. from real world guns.

Hornandy is mid powered at best.

Federal is a joke.

if DT (Mike McNett) ever got back to basics id come back to his ammo, until then hes not doing anything grand, anymore anyway.

The original Norma loads were HOT.

Hey 681
I was originally interested in the 135gr also but there
is an online youtube test of various 10mm loads and I cannot
remember where but the 135gr Remington HP completely disintegrated
in gelatin at 10mm velocities.
I am attaching a photo of the bullet fragments left over.
That is why I moved up to 150 -165 gr loads.

It could well be that the Nosler 135gr is a lot tougher... we
need to look into it dont we.

I am of the general(very) opinion that the wound channel volume
of all bullets of different configuration are similar, it is just
that some wound channels are shallow and large in diameter
and others are very deep with narrow diameter. This is seen
easily in the gelatin photos of bullet tests. Like you,
I would rather have 12 in of penetration with a 5 inch wide
hole instead of a 28 inch penetration with a one inch
wide hole.

Hornady 7th edition manual, page 861.

15.1 is the max for AA no 7 and velocity is 1450.
14.6 is shown as 1400 FPS.

Good luck with your research.

for private citizen defense i dont have a problem with that 135gr. 10mm round having jacket and core separation if it creates a massive wound and still penetrates well. this is not using the fbi gel results. they are using homogenous media and want ~12+" due to light barriers that migh be encountered like a car door or windshield.

there is a you tube vedio series of a guy using DT loads from a G20 firing through a refrigerator, car wind shield, pork ribs, "jello" and a cow heart.....i like what i saw the DT 135gr. do.

i will try to google and post the link.

this same guy does other "tests" with DT ammo on real world stuff. of course he didnt chrono the speed of any of it....

I recently bought a 1006. My previous 10mm experience has been with a Colt Delta and Norma ammo in the early '80's. The gun exhibited marginal accuracy, lots of hammer bite, and a pretty stout kick. The kick didn't bother me that much, but the other detractors did.
I bought some Remington factory ammo, as well as some Georgia Arms ammo advertising 1250 FPS 180 gr. FMJ. It was about the same power level as the Remington, judging from the recoil.

My handloads consist of some 180 FMJ's loaded to a middle of the loading manual road load, and some 175 cast bullets loaded to 950+/-. The cast bullet loads are pretty wimpy, but they happen to be very close to the original notion of the .41 Mag police load, ie .40 cal/200 gr./900-1000 fps. That was supposed to be the ideal combination as a self defense loading. This load makes an ideal range load for me. It knocks down steel plates with pretty good authority, is comfortable to shoot, accurate, and doesn't throw my highly prized 10mm brass too far into the weeds. If I were going to hunt with the 10mm, I'd load it hotter, and likely buy a 610 to shoot it in. Not that the 1006 wouldn't handle it. I really don't want to abuse the gun or myself, since repair parts for both may be short supply.
To me, it's interesting to have a gun capable of some really high performance, but I have little need of the really hot stuff. With the weight of the 1006 I can easily put multiple hits on target very quickly with the milder rounds. This makes me smile.
