10mm Education requested

There is a possibility that a 10mm Auto could be in my future, and I was just looking for some information on it.

What kind of information? Is the kick 'bad' when compared to .40 S&W and .45 ACP?

When I get into reloading, can it be downloaded efficiently for fun, cheap target practice?

Does it suffer out of shorter barrels like .45 is said to, or does it still get sufficient velocity to expand?

Is it the 'Magical Bullet'?

(I know...placement, placement, placement.)

Use the search function here and at TFL. There should be answers to any questions you might have.

www.glocktalk.com also has some excellent information on the 10mm.

priv8ter,

If you are used to 40 and 45 then no. I shot 45 exclusively for years before rediscovering 10mm. I can not really tell the difference depending on the gun I use. Funny how much a difference that seems to make with 10mm.

When I get into reloading, can it be downloaded efficiently for fun, cheap target practice?

Yup. One of the cool things about 10mm is that if you load it soft, it recoils soft. Load it hot, it recoils hotter. There is flexability that does not exist in 9, 40, or 45.

Does it suffer out of shorter barrels like .45 is said to, or does it still get sufficient velocity to expand?

Well you probably won't have a short barrel, but if you do it should have plenty of velocity. The hotter loads are screaming anyway, so a drop won't be noticable.

Is it the 'Magical Bullet'?

Depends on the load & bullet. I trust it with my life. I use a couple different loads for defense--for summer and winter. I have seen the expansion first hand after going through building materials, and it was impressive. I would trust 45 and 40 as well, but I like the reach and accuracy of the 10 in my rural locale. As you said, placement is important.

priv8ter,
You generally do not want to go below 4" on the barrel of a 10mm firearm. (The glock 29 makes up for it's 3.8" barrel with the polygonal rifling.) The reason is because nearly all 10mm autos have 4.25-5" barrels and therefore the powders used in the ammo are slower burning than needed to get the bullets moving fast enough to be effective. Velocity attrition in sub 4" barrels is really pretty staggering...

The glock 29 was exactly what I was thinking of...

The Glock 29 is my rural carry choice. Similar recoil to the Glock 30 in .45 but the recoil impulse is a little different. Great gun. You won't regret it.

The recoil from my G29 with my loads (200XTP @ 1175fps, G29) is quite controllable. I can load down to sub-.40 levels if I so choose and the factory spring will cycle the action smoothly. And don't listen to the naysayers on velocity. Take a trip to the 10Ring at Glock Talk and do a search for "MCNETT G29", you will find some of my research into this exact subject.

I own a G20 and reload for it. The 10mm is, in my opinion, the most versatile auto cartridge on the market. Period. You generate loads that go from wimpy to diesel as fast as one can say "Damn. That dis not suck."

poof...

My Glock 20, firing a West Coast 180 grain plated flat point, over 6.5 grains of Unique with a Winchester primer has less felt recoil than my Kimber Custom II firing a Berry's plated 200 grain flat point over 6.5 grains of Unique with a Winchester primer. Does that help?

Blades67 is making a good point. You can play with the 10mm loads and get some pretty neat affects in terms of recoil. The comparison to 40 is interesting in this respect. You can get lower pressures with the 10mm at the same velocity and bullet weight. That coupled with a generally heavier gun with heavier springs means you get less felt recoil with 10mm than some other calibers with similar performance. I have noticed this particularly in my 1076. It handles fast with the "FBI" loads.

In my TOTALLY objective opinion I would have to say that the 10mm Auto is the best cartridge you can get for an autoloader! It can do everything a 9mm, .40 S&W, .357 Sig and .45 can do, and better.

Did I mention that I like it? :D

I never thought it was that much more powerful until I borrowed a friend's glock 20 to shoot a steel plate match. (Instead of my .45, for more capacity.)
You should have seen the steel dance!
Let's see, what's more firepower?
15 rounds of 10mm, or 8 rounds of .45?
Hmmmm, let me see....
I bought that very gun a few weeks later, to be followed by another 10mm, 6 months later.
