What’s so great about 10 mm?

[Longcarbine]

I have a S&W 610 4", a Ruger GP100 4", a Kimber Target and a Rock Island, the Smith will out shoot them all. But yea! it's just a way to shoot an auto cartridge in a revolver, but in my book it's a good way. I would put the 10mm some where between .357 magnum and the .41magnum. It is very accurate!

One thing I've noticed:

Internet wisdom says, "If you're ever accosted by an angry bear, you'll have time for only one or two shots . . . . "


Then you look at actual encounters, and that's not true at all.


Update: Handgun or Pistol Against Bear Attack: 93 cases, 97% Effective

Sort of like the internet wisdom that says "If you can't take care of a criminal attack in three or four rounds, you shouldn't be trusted with a firearm . . . ."

And then you look at actual encounters . . . .


The real world lesson is that you might need more ammo at hand than you, or other folks, think you will need.

So the 10mm semi-auto handgun has a purpose: to spit out 16 rounds of .357 magnum equivalent loads.

Cant speak specifically about the 610 but can about the 10mm cartridge. What's so great about it to me is the fact that I load bullets from 135gr all the way up to 200 and 220gr ones are out there too. It's no 44magnum, it's not even a 41 magnum but it's a thumper for sure, dont doubt it. I've loaded 1560fps 135gr all the way up to 290gr Nosler HPs with 12.9gr of A#9 going 1187fps. It's a very versatile round. I run into people at ranges who've never heard of a 10mm, new shooter obviously, but it's fun to get people talking.

My Dan Wesson Silverback is a very accurate gun too. I definitely changed the springs, both the recoil and main and added a flat bottom fp stop. And the 10mm, for me anyway, seems to be plenty accurate.

Last night I loaded 100 180gr Speer Gold Dots over 11.7gr of A#7, one of my Silverbacks favorite loads.

I love 10mm in autos, and have both a Colt Delta Elite I bought when they were first released, and an AMT Javelina longslide (7-inch barrel stainless 1911). But I have always felt that rimless, short semi-auto calibers were dumb in long-cylinder revolvers. That's why we have 357, 41 and 44 Magnums, and 45 Colt.

I continue to be amazed that people will willingly part with money in exchange be for a revolver chambered for a semi-auto caliber....

NOTHING. It's just something to sell. If you already have a solid .45 automatic and some sort of magnum revolver that begins with .4x there is no need for one. If you are one of those exceptional people who can actually use a real, honest handgun (one you can actually wear on your belt) at 100 yards and beyond, then the 10 might have something for you that the .45 doesn't, but certainly nothing that your .41 or .44 Magnum revolver can't easily keep up with - and exceed. JMHO.

Hahaha! Truth spoken at it's finest... 10mm is a FINE round "IF" you either roll your own or carry Buffalo-Bore, Underwood's "Boutique's" or now Sig-Arms makes a fine load as well. Other than that you get a .40Cal (also a another fine defensive load for 2 legged buttholes) just added with 40-50fps pushed into it.

Where 10mm really shines is it's 220+ grain load threshold offering at 1200fps with a pill that is either a truncated cone bonded HP for the "skreets" or a "Keith Hard Cast" for in the woods or fields. Other than that you are carrying a common .40caliber.

If I was to be a goin' to Alaska to hunt or fish, I would not feel the need to carry a side arm. That's what I'm paying the guide for

It's different and although a .40 caliber, it is more. At one point my thought process was not to acquire any one off calibers like a 10mm, .41 magnum, .32 magnum or .327 magnum.

I failed when a Colt Delta Elite presented itself at a bargain price at one of the local pawn shops. I had just finished reading a thread about the 10mm and became, like an eight year old in an ice cream parlor, mesmerized by all that was not vanilla.

The Delta Elite had a couple of finish issues and became the only the second firearm that I had refinished. I also added Novak night sights for all of the night time shooting that I enjoy.

Then the quest became to find a Mod. 610. The search ended with another true bargain from the estate of a departed dealer. It was NIB and like Medusa, drew me in to its spell.

The fact that both are exceptionally accurate is a big plus. Not to mention that the 10mm is everything the .40 is not but, that is my humble opinion.

I also succumbed to the allure of the .41 magnum. Now there is a handgun that will do everything a .44 can do but, it won't replace my .44's.

 

[Loyaljeeper]

If you don't understand the 10mm you have never shot one. Seriously! A friend brought a Glock 20 to a shoot, and everyone there fell in love with it to include my wife. There are Glock haters who love a 20 because they love 10mm. I fell for the 10mm in an auto platform and then decided to try it in a revolver. Once again, 40s&w ammo proved to handle the ammo shortage better than any handgun caliber. Guess who can still have fun at the range with a revolver. The answer is people saw this coming and stockpiled or those of us who have revolvers chambered for 10mm.

 

[jtcarm]

What kind of bars do you frequent??!! Lol

OP, I think a 10mm shines in an auto. If you have a 41mag or even a 357, I wouldn't get it unless it was to collect.

Bear bars?

I went to a Bare Bar once. There weren't any bears[emoji20]

I own a GP100 10mm. I have yet to seriously wring it out, but it's a nice gun, accurate, and the DA pull has changed my opinion of Rugers a bit. It's a .401 on a medium frame. If they'd build it in 6-shot .41 magnum or even .41 Special, I'd join that cult.

A 10mm N-frame isn't my thing, but people setup for 10mm who want a moon-clipped revolver, it might be just the thing.

 

[PatriotX]

I had a Colt Delta Elite, it didn't shoot to my liking with anything but 40-level Ammo. Gone.

Found a Glock 40 in 10mm, loved it.

Shot a 610, sold the Glock. Looking for another 610.

I suppose the biggest fan of the .45, Col Cooper, who thought it necessary to take it up a notch with the 10mm, didn't know his stuff.

 

[tlawler]

The 10 in a semi auto is fun to shoot, no doubt, and I have several including a 1026 and a CS40 converted to 10mm(but NO Glocks!)

But where the fun really is for me is in the 610. In the current primer crisis, I don't burn through ammo nearly as quickly with a revolver as I do with a semi. I savor every shot and take my time and really aim. Even when I'm not trying so hard, I seem to be inherently more accurate with the revolver in DA. And hitting the target more accurately gives me a greater sense of satisfaction.
Here's a target from a while back at 12 yards which is the limit of the indoor range I frequent.

 

[oldman10mm]

After 25 years of shooting my 1006, for which I reload from 'mild to wild', I picked up a 610 (pre-lock 6.5") and enjoy shooting it more than the 1006, probably because I'm more of a revolver person than I am a pistol person.

[S&W-Keeper]

I like the 10mm, because they don't make a 11mm.I have a 610 and a Glock.I like both of them.

 

[smithra_66]

I like the 10mm, because they don't make a 11mm.I have a 610 and a Glock.I like both of them.

Actually they do. It's called a 44 special and 44 magnum.

in all seriousness, I would say that the 10 mm is a trendy round. It's not one of the old standbys that will never go out of style like the 9x19, 45 auto, 38 spl, 357 magnum, etc.

I remember a time when it was completely out of vogue and almost dead in the 90s and the 40 S&W was the darling of the gun world. Now that has flip flopped.

I'm sure there will be a time in the not-too-distant future where the 10 goes back into obscurity depending on the newest and latest trend of the day.

It's current claim to fame is as a high capacity autoloader caliber in bear country. I'm sure it performs that job just fine.

It also seems to be in vogue for hog hunting out of revolvers, but personally I don't see why you wouldn't shoot the 41 or 44 mag if you're going use a revolver. More power and you don't have to deal with clips.

 

[BLUEDOT37]

If the (orphan) 41 Magnum can stand the test of time with it's historically very limited offerings & availability of components/ammo, what makes you think that with the 10mm being produced in more offerings than ever & the wide availability of .40/10mm components that it's just going to disappear.

Yes, I agree the 10mm is a better pistol cartridge than a revolver cartridge but the 45ACP is a better pistol cartridge than a revolver cartridge & there have been revolvers made for it since 1917.

If someone ever takes the effort to get the 10mm Magnum SAAMI certified, look out.

Did anyone make 10mm AR? I could dig that!

 

[BLUEDOT37]

10mm Auto Rim

Did anyone make 10mm AR? I could dig that!

No not yet. Maybe if we keep bugging Starline they will but so far they're not interested.

Probably because there would be SAAMI certification to deal with since it'd be a new cartridge?

For now you have to make your own.

I made a few from 41 Magnum cases. They still need to headspace on the case mouth but the 41's rim allows for ejector extraction. It's not worth the extra effort to do more.

I largely shoot my 10mm Auto & 10mm Magnums without moonclips anyway.

[Bhfromme]

The 610 was a great shooter but after buying a S&W 69 I realized in a revolver there was nothing 10mm could do that a 44 couldn't do better and sold the 610.

I have to respectfully jump in here. With full moon clips on your belt a 10mm revolver reloads much faster than a .41 or .44 magnum.

Oh wait, you meant 10 mm Auto Rim cartridge.

NEVER MIND!

 

[asilcot]

Really? Must be a glock. My single stack 1911 & 1006 only hold 9. ! don't do glocks.

My XDM holds 15 and my Banshee factory mag holds 30. But even the 1006 with 9+1 is a step up from the revolver. (Yes, I know. Weight too).

Did I mention I REALLY like 10mm?

 

[Autonomous]

Really? Must be a glock. My single stack 1911 & 1006 only hold 9. ! don't do glocks.

Understood about the Glock thing.
When I decided to buy a 10mm a poly striker fired gun was high on my priority list. With the spectre of buying a Glock looming I was happy to learn of the XDM and even happier when I liked it.

 

[BigBill]

I stuck with my 1911a1 in 45acp through thick and thin in the past many decades when new auto pistol calibers came and died by the caliber grave yard. Way too many to mention.

Now it's been said the 10 mm is equal to the 41 mag, I believe it's not, I don't like using moon clips anyhoo.

Now isn't the time to consider adding another new to me caliber anyhoo.
But I'd like to jump ship and get a ruger bh in 45 LC I have others in 45 lc.

When I first shot my m58/41 mag, do you remember your very first kiss.? Lol

How many rounds do we really need? I post some real shootout videos but I'd get banned.

 

[Autonomous]

The 10 mm is hardly the equal of the .41 Magnum, .357 Magnum is more like it.
Still, some smart, experienced people are converting to it for woods carry.

 

[local_dirt]

A couple of months ago I found 14 boxes of 10 mm fmj for $23 a box so naturally I bought all of it. A friend gave me his dies, some primers, .40 casings and about 3000 hard cast bullets, so now I'm looking for a 10mm Smith and some moon clips, lol.

I have a 4" 57, but it's too nice to shoot and ammo is $25/20 rounds--ouch!

Roll your own. I stocked up on .41 mag components a few months back. Much of it from this forum.

And no, you don't need a 610 if you've got a .41 magnum, other than if your sole intent is to shoot 10mm (semi-auto ammo) from a revolver.

I belive the CMMG Banshee comes in a 10mm chambering

My 57 nickeled 6" 41 Magnum, 1006, 610 6.5" 10mm.

 

[Dan Christopher]

The 10mm gives you better than 45+P velocities ( and with even more room to stretch its legs ) and it does it with more efficient, sectionally denser bullets.
