Not another .45 vs 10mm thread...

[Rock185]

I wouldn't want 10MM in my .45s either. I've been a 10MM fan since Bren Ten days, and initially had a Bren Ten and have had a 10MM of one kind or another around here since. The 10 and .45 each have their place, and are both fine cartridges.

BTW, back when the Bren Ten and 10MM were brand new, some of us picked up Michael Dixon and Tom Dornaus in Phoenix and drove up to Gunsite. When Col. Cooper was shooting some knock down targets with the new Bren Ten, he commented that the 10 knocked down targets better than the .45 at 50 yards. He continued, saying he didn't know if that mattered in a combat pistol. I don't know either, but still like the 10MM.

Depending on what you'd like to do with the extra power (More velocity, More Energy, More Power factor) that the 10mm offers, then YES it matters.

I have not had to purchase factory ammo for 10mm or 45 in quite a long time, but today i just looked at the difference in price....if I was a brand new shooter looking for a big bore semi Auto FULL size weapon, I would choose 10mm. Price difference between 45 ACP and 10mm factory ammo is negligible at this time.

I own 9mm high capacity guns for defense/carry.
I own 357 Mag wheelguns for deer, boar hunting.
I own 1911 .45s for nostalgic purposes, and love the feel and the way they shoot.

I got into 10mm autos... and they are able to cover all 3 of the roles.... high capacity in Glock 40MOS (15 rounds) The 10mm has the same power of the 357 Magnum, and its offered in several awesome 1911 platforms. In a way, i could have 10mm replace all of my pistol calibers for all practical purposes. But i aint gonna do it, but props to 10mm.
The 10mm can wear lots of hats

I am a 1911 guy, have been for well... let's just say 40 years plus. (Actually shot my first 1911 more like 55 years ago, but didn't own one until the stated 40+ years ago.)

Bought a 10mm 1911 (DW CBOB) about ten years ago. Took me a little while to bond with it, mostly due to the fact that it did not work correctly out of the box. Eventually got those issues resolved and I now have an appreciation for the round and the pistol.

I will admit that most of my 1911s are .45 acp and 90% of my shooting is .45acp.
But I am in no hurry to divest myself of the 10mm, and am handloading for it.

 

[JR24]

More and more I only bring one or two calibers to be range, usually one rifle and one pistol. Makes mistakes easier to avoid. Doubly helpful since most of my rifle shooting lately has been .223, .300 BLK and 6.5 Grendel, all in ARs and all potentially using the same mag (or at least cosmetically so, for the 6.5) so I make sure to only bring the one at a time to avoid potential explosions.

And I like both .45 and 10mm, both are great and have their uses.

It happens.

My FiL managed to load a 380acp cartridge into a 9mm service pistol.

It chambered and fired, but he had to take it home and fool with it to remove the jam.

I fired 3 rounds of .380 from my Beretta 92 before I checked to see why I had just had the first 3 FTE's ever with that gun. Not bragging--it was a major failure of attention and a learning experience. I was a little surprised that a simple pull-and-release was all it took each time to keep on truckin'.

I guess .380 in a 9mm is one of the least unlucky "wrong cartridge" situations.

10mm has won me over BIGTIME
If youre a handloader, the reasons are obvious.
10mm can be loaded down to 45ACP performance and accuracy. Also chambered in the same platforms. Also can load 10mm to almost double the power of 45 If you so desire. It probably has to do with the 21,000psi 45ACP to the 10mms 37,500psi abilities. If youre a hunter of any game animals, this is an entire world of difference.

Now, 10mm is currently less common than 45ACP, so finding and keeping an ample supply of Brass is the biggest challenge for a handloader (or any component in this day and age for that matter)
If i did not handload my own, I would consider this quite a bit differently.

45 ACP was developed about 115 years ago.
The 10mm came out about 80 years later. This comparison is not and shouldnt even be a fair comparison because it is not Apples to Apples.

Is Tiger Woods a better golfer than Jack Nicklaus?
Yes. But .........

I bought the Glock M40 MOS and I love it. Of Course I have a TON of Goodies For It. I also have an extra Lower for My MeckTeck Conversion Rifle. The Pistole has a LW Ultimate Adjustable Trigger Installed. A 9 inch LW Barrel and a Alpha Wolf Threaded Barrel and their Compensator on it. Also a a quick detach bipod for the pistol. This Thing is a Blast {Pun Intended} to Shoot and Reload for. I Bought a couple thousand new Star Line brass for it. This is My Fun as Hell Gun. Had to buy the extra lower because The Trigger Mods I did will not work with the MeckTeck Conversion Rifle.

 

[Flatbush Harry]

I have, use and carry both in Springfield TRP 1911s. I use the 10mm when hiking, hunting or fishing, and the .45 ACP for daily CCW. The 10mm is nearly a .41 Magnum and gives me one extra round over the .45 ACP. I've also carried a .357 Sig Glock 33 when hunting or fishing as it's the virtual semi-auto equivalent of a .357 Mag. Here in CO, we don't have many big Bears. If you encounter an angry Griz, a handgun is unlikely to be of help.

If my handgun collection was a collection of 1980s era action movie stars....my Glock 40 MOS would be Arnold Schwarzenegger, Steven Segal, and Sylvester Stallone all at the same time. Im with you.
Fun as hell and highly effective for whatever youd ever need a gun for.....aside from IWB carry.

If you handload your own 10mm ammo, then this gun becomes Chuck Norris.

You Got That Right. Only Gun I bought as soon as I could get my hands on it. I do Handload for it. Got about two Thousand Brand New StarLine Cases that I can work With. Also Only gun That I kept my promise To myself to sell a gun to help Pay for it. Sold a nice Ruger 44mag Red Hawk to my Nephew to keep it in the family. He Loves it but it just beat me up to much and I won't shoot 44 special in it. Love all the after market Goodies for it too. Nice having all that Power Potentials in a Pistole that doesn't beat me up even with heavy loads. But you still Know you are shooting a Power House Gun. Cost a few Pennies More to handload for as I was already set up to Load 40 S&W. Same Bullets a touch More Powder. I love That. Yep My Bad Ass Baby.

When I work up 10mm with 180-200 grain jacketed whatevers, using Powders [including but not limited to] Longshot (favorite), Blue Dot (second favorite), Power Pistol (3rd best), AA#9 (does the job swell too).... I get 357 magnum velocities with heavier bullets, magnum booms, and they take care of bowling pins quite nicely. And to have 15+1 rounds with this kind of power feels like cheating.
....And i was about to get a special 357 with an 8 round cylinder for the extra 2 rounds of magnum power! G40 shut that down in a hurry.

No, the 10mm is not even close to a .41 magnum....but about equivalent to a .357 magnum. Nevertheless it is still a good cartridge.

I researched this further in several of my reloading manuals. You are correct that 10mm in most loads generates less velocity and energy than the typical loading of a .41 Mag. I was incorrect in so stating. Thank you for correcting me and pushing me to further research. I'll go back to my S&W 629 for woods carry as I did for years. I do like the 10mm in the 1911 platform though.

Cheers,

Harry

I have a DW Razorback 1911 in 10mm and I like it quite a lot. For woods carry I think it is a fine choice and I would not hesitate to do so here in Idaho.

My typical remote wilderness area back-country revolver is either a .45 Colt Mountain Gun or a 4” 629-4.

 

[Rock185]

Having loaded for Magnum revolver cartridges, .45 ACP, and 10MM, etc. I agree the 10MM is more in the .357 power class than the .41 Magnum class. Recently testing production Buffalo Bore 10MM 180 grain and BB .357 180 grain in 4" revolvers for example, the .357 was just over 100 FPS faster. I compared BB, and mention it here, because BB is usually considered some of the warmer factory ammo available in both calibers....
