10mm coming back in style?

[ilbob]

I have seriously considered getting a 10 mm Glock. It would be my only 10 mm and my only Glock firearm. A guy let me shoot his down at the range one time a couple years ago. Surprisingly little recoil and easy to handle even in a fairly compact size. But I have been unable to convince myself that I need another caliber so I never did it.

You are not trying hard enough
Seriously though that is the one thing that REALLY bummed me when the state started making it more trouble that it was worth the buy and sell here. If I won the lotto I would end up with a gun collection like in some of those fantasy movies. I used to love being able to buy something, play with it for a good while, something else would catch my eye and I would sell one to buy that one. It's no longer worth that so a lot of stuff is left "wanting". Of course these groups don't help. Used to be I only had trouble saying no to myself if I was at a gun shop. Now it's when I see pics of other stuff, so much of it looks like "Damn I would like one of those."

 

[Zaydok Allen]

Yes it's popularity has increased. That's great news. I got into it once I started loading my own ammo.

It's a highly useful cartridge and is still not offered in as many sizes as I'd like to see.

Reading through this discussion, caused me to recall something I read years ago. The gist of it was that fashion runs in ~30 year cycles. Maybe cartridge popularity is similar?

If so, I may be back in style again

I love my G29.
Shoots softer than I expected when I bought it.
Loves 200gr ammo.
Perfect POA/POI.
I carry 200gr handloads daily in it.
XTP or Flatnose Lead.

Edit;

I agree it has gained some steam. Happy I stacked brass/nickel for it awhile back.
Need a few more magazines though.

Is it just me or can Glock 10mms not handle any bullet weights over 200gr reliably with a stock barrel? Try as I might with a pard’s 20, it just can’t get the velocity up. We also can’t get any 180-200 gr over 1200fps....so....I just don’t see any practical benefit of the 10mm over a 45 in comparable bullet weights.

On the other hand, the 155gr 40/10 has a similar SD to a 125gr .357, so that’s interesting to explore.

 

[Rock185]

Anchorite, While I like the 10, have to agree the .45 ACP is hard to beat for a general purpose semi-auto pistol cartridge. I had a G20, didn't care for it, didn't keep it long, and can't recall if I used it to chronograph any ammo. Within my humble experience 1200 FPS, or a little more, is about par for the course with 200 grain 10MM in 5" barrels. With the 10MM 180 I've seen about 1320-1380 FPS in 5" barrels.

 

[Fishingted]

Alaskamike- Yes. I agree, the 10mm is a great cartdrige to handload. Powders like Blue dot, Power Pistol, Longshot, AA #9 and BE-86 all rumored to get 10mm cooking to full potential.

I load longshot, Blue dot ,CFE Pistol, and Unique in the 10mm. Unique is my main Target Powder.

 

[Fishingted]

I find handloading 10mm extremely rewarding, and economical. Dont like chasing the brass though!

I have a Dillon 550 and was already set up for 40 s&w so loading 10mm was no problem. Same Bullets a tad more powder and that's it.

My Glock 40 MOS is the first gun I bought as soon as I seen it. It is just a Hoot to Shoot. It is simply my FUN GUN. That big Oh Beast Tames the 10mm recoil really nicely. Must say I have a lot of toys for it. Including a Nine inch LoneWolf Barrel. A threaded Barrel with a Compensator on it. Both these barrels Suck up a Lot Of Recoil but I don't mind running the Stock Barrel as well, and a Quick disconnect Bipod. Being a re-loader that already loads 40 s&w The 10MM is a pleasure to load for. I run Long Shot, Blue dot, CFE Pistol, and Unique. I use Unique a Lot for Practice Loads. With the Compensated Barrel the recoil is about somewhere between a 9 and a 45. It rolls out the cases pretty close to me but still runs the gun great. I also have played with trigger a bit; with a ghost connector Trigger spring. and a drop in Ultimate adjustable Trigger. Got a Meck Teck Conversion Rifle also. Had to buy another Lower Frame because the Meck Teck will Not work with the Trigger set up in the original Frame. Like I said this is my Fun Gun. It is a Blast To Shoot but doesn't Beat me up Like the Redhawk 44mag that I sold to help Buy it.

I'm down to my last 2 10mm (Colt Delta Elite and SAI TRP) and a few hundred rounds of ammo. Jeff Cooper would be proud of me.

Har3ry, the 3 is silent

I've had my fair share of 10mm's, it's a good cartridge for sure. Personally I don't really see the point of it, mainly because I don't see it really doing anything that other service cartridges like the .40 or .45 aren't doing, and certainly not for the premium in price. if I feel like those aren't enough, I'll grab a revolver. But again, that's just me.

The same can really be said about 90% of the cartridges currently being made. But what fun would it be without them?

Do you have any 10s for sale?

 

[Zaydok Allen]

The 10mm is definitely enjoying a resurgence. It ain't the bear cartridge that many seem to think but it quite capable for deer-sized game. I've had .38-40's for years and added two 10mm's over the last year or so.



You repeat this every time, along with the nonsense about the .45/70 and it's still false. The 10mm gets compared to the .41Mag quite often but folks must be comparing full-tilt 10mm to low end .41Mag. The 10mm simply doesn't have the capacity for anything heavier than 220gr and comes nowhere near heavy loads in the .41Mag. Considering that I get well over 1100fps out of a 355gr in a 4 5/8" .44Mag, I'd say that's WELL beyond what the 10mm will ever be capable of.

Agree. I can hardly bring myself to even come into 10mm threads any longer due to the repetitive spewing of inaccuracies.

The only logical comparison to a revolver cartridge is a 10mm is fairly close in power levels to a 357 magnum when loaded properly.

I don't understand why we don't just compare it to other semiauto cartridges? It sure would keep these threads cleaner.

What powder are you using? I regularly push 180 gr FMJs to 1225 fps with less than a full load of AA#9. Max or near max loads should pass up 1200 fps with that powder.

Edit: Longshot ain't bad either.

 

[Palladan44]

Something interesting ive been thinking about lately is the terminal ballistics of the hollow points in 10mm. Many, but not all of the .400 dia. (In my case 180gr. bullets exclusively) hollow points were designed for the .40 s&w. They were designed for expansion at 975-1100fps. (Such as Barry's plated hollow point) Run a bullet up to 1,300 and it starts shearing petals, fragmenting, splitting, etc. and behaves very erratically upon terminal impact. Some of them will wind up penetrating quite a ways past what theyre looking for.
When I hand load for 10mm, i keep all of this in mind.

Theres a reason why some Manufacturers load their 10mm to just about .40 velocity. 10mm "harder bullets" like hard cast will "over penetrate" by miles, and in a self defense situation I believe some of the harder jacketed, slower opening hollow points go a long ways in Gel as well. Well beyond the "target" for which they were designed. From the feedback ive collectively gathered, the 10mm loaded to its full potential with "strong" bullets only, is a hunting game gun or woods defense gun and not really necessary for SD carry against human threats.
I do like the fact it can create around twice the ballistic energy of the world-wide favored SD caliber, the 9x19. One extra millimeter, double the power.

I’ve liked 10mm ever since I was issued an MP-5/10 in 10mm back in the ‘90s. I have a great Vaquero and a DW Razorback, both 10mm. And I hand load my own ammunition.

what agency issued 10mm mp5s?

That would be the only reason I would have to get a 10mm; the ability to drive hard cast bullets really hard in an effort to get good penetration on big bears. I live in SW Montana maybe 80-90 miles Jellystone and we have some of the highest concentration of big Grizzlies in the lower 48. Something like a Glock 20 would be a good hiking & bushcrafting sidearm. Nowhere near the power of a .44 Mag or .454 Casull but easier to shoot and higher capacity.

FBI starting in the 90s, not sure how long it lasted, I know the 10mm pistol was short lived with them. Not sure how long they kept or if they still use the MP5/10 in a limited role or if its phased out or what.

I once knew an HK rep back in the 90s who claimed that the very, very few 10mm MP5s loaned to the FBI were beat to hell quickly by ammo and thus dropped from production by HK. Wether or not this is true, I do not know. But I do know there were some 10mms, because I actually held one in my hands.

 

[Palladan44]

The 10mm still is issued in Government roles.

Certain hostage rescue teams use them...why???, because they want to increase the odds of stopping a deadly threat with a single, first shot. Period.

Might I add that these teams are well trained and hand picked for their tactical/marksmanship skills, so they pass high level qualification tests with their 10s without issue.... Something that general LEOs have historically not been able to do, according to the FBI.... Theyre not worried about over penetration so much, its that the guns are too big for smaller handed officers, and qualification scores drop due to heavier recoil of the 10mm...so they went to the 40, and now were slowly dropping the 40 for the 9mm for some of the same reasons...including improvements in bullet design, and some cost savings.

Agencies the further North you go, are more likely to pack something like a Glock 20, for the added power to kill larger and potentially dangerous game animals.

Yup, ive heard the same as well.

The 10 is definitely coming back in popularity. New pistols are constantly being introduced in it. There is one on the cover of this month's American Rifleman magazine. Of course, the ammo availability issue makes everything more complicated lately. The last thing I would do right now is buy a gun in any "boutique" caliber. I would be tempted to buy a Glock 20 if I lived somewhere that there were critters I may have a problem putting down with 13 rounds of 45 from my Glock 21, but that isn't a problem here in Fl., so I'll just stick with what I got.

I agree. If you can load your own, you can get 180s to 1,300. Blue Dot or Longshot. Then were talking 10mm performance as originally intended. Theres are reason lots of factory 10mm ammo is not loaded to full potency....if its hollow points for SD, theyre looking for certain expansion and penetration characteristics and around 1150-1200 is damn fine at doing lots of damage. At 1300, lots of hollow points start to either over penetrate or shed petals, and decrease their weight retention, or sometimes shatter. There are exceptions to this.
Hard cast or JSP (if you can find them) are a really great 10mm projectile if youre going for Max Velocity, Hornady XTP hollow points stay together the best at high velocity (compared to some others), ive found through my personal tests.
10mm can do some things that no other service caliber semi auto can do. Thats why the 10 is a great one...
