10mm or .45ACP?

For you "power seekers" ----- there is also the 10mm MAGNUM --- it was made to be used in Irwindale Arms, Inc. semi-auto pistols. It can launch a 200gr.at 1400+fps.

BTW -- Starline still makes brass for the 10mm Magnum.

Idaho, you ought to take those numbers with a grain of salt. There are numerous threads here on this forum alone that address the inaccuracy of the reported velocities by the various manufacturers.

I have bought alot of DT ammo for 9mm and 10mm and most of the stuff i chronoed have averaged +/-10fps of their advertised velocities. Some was faster than advertised, some was slower. Most people would be fine with these results. Most would probably ask for a refund or discount on their next purchase if their pistol ammo 50fps slower than advertised. But in no way can a business keep running, with 99% of their customers happy with their products, if they were selling/advertising 240gr. 44mag ammo thats 320fps slower than what the customers were actually getting(1500fps their chrono vs. 1180fps of of the velocities in your source).

There may be some innaccuracies but not 300fps slower like youre suggesting

I didn't quote only "one guy", did you not notice the mulitple sources I linked? Most of these sources used actual chronograph readings as opposed to manufacturer's numbers. Did ALL of these authors and reviewers make up numbers to "help" prove their point too?

Im sure those are actual chronographed readings. They arent lying by any means but they sure as shi* arent painting the whole picture. They are comparing a max load .460 Rowland to a light load 44mag. It just isnt honest. Its like saying a honda civic is faster than a corvette when the corvette is stuck in 1st gear and the honda is going through all of them. So in other words, yes, they are throwing out low numbers for the 44mag to make hype the 460 rowland


I think the 460 rowland is a good caliber but youre saying its something its not. A 10mm is basically the equivilant of the 357mag. But there are some 10mm koolaid sippers that say its inbetween the 357mag and .41mag, which it isnt. Theres a big difference in power between the 10mm and 41mag just like there is between the 460 rowland and 44mag. I think you need to put the glass of 460 koolaid down, step back and look at the whole picture.

i love both my glock 20 (10mm) and glock 29 (10mm) and the glock 21 (.45 acp) but carry the g20 and g29 most of the time. more ammo on tap, less recoil for me and when shooting steel plates it really hits them hard. .45 is going to give you more ammo choices but if you get the 10mm get a press and plan to reload....

I just read this entire thread...wow. The 10mm is a very versatile choice and would have been more of a sales hit if the Bren Ten stayed around back then. The other thing that lit everyone up about the 10mm was that HOT Norma ammo.
I bought four Brens with mags back in 85 or 86. Same design as the CZ and its clones, FIE/TZ/EAA etc.

Most factory ammo falls far short of the cartridge design potential. Same goes with the .38 super

The .45 is an awesome cartridge, but I cant help but feel the 10mm/.38 super
have more potential versatility that are yet unexplored.
You can crunch all the numbers you want, but the only math that interests me is found where the blood spills.
The .400 caliber cartridges be it in a handgun,revolver or rifle seem to have a magic about them.
Its probably my imagination, but there seems to be some ballistic sweet spot there. IE 408 Cheytac, 10mm/41 mag, 416 rifles etc.....get the Ten and enjoy it.

....and dont shoot deer with a pistol at 185 yds. You would be an Idiot
Just my opinion. Chuck Warner

neither

.357 or .44 for the woods.

I carry the .44

Different tools for different jobs.

My dos centavos.

.....I have spent a lot of time in the mountains in the Pecos Wilderness here and ballistics notwithstanding, the 1911 platform rides better on a horse/mule and the spare ammo is easier to carry. May not mean much to some, but I would rather have 10/11 rnds of 10mm/9X23/.38 super at hand than six of anything else. This is a good crucible for whats comfortable in an urban environment as well
Lots of realistic reasons besides knockdown power. Any of those above will take anything in this state if needed. The small loss of energy is more than made up for in capacity and portability.
The 10mm fits that bill for me best and Thats why I recommend it.
I have a little experience with all of them and with shots in the woods here...15 yrds is a long ways...we have oc/cc here and I do both with the same.
But to tell me neither when just making a recommendation is interesting. I would tell you EITHER.. Chuck

I'm not going to say that Chuck (Chuck@AC) knows everything there is to know about guns, but this is the Delta he built and I am now the proud owner. It is every bit as good as the 2 Les Baers I have. The man knows what he's talking about.

you can't just swap the barrels. the breachface is different, the firing pin location is different and last but not least the extractor and the ejector won't work.

you lost me ROBBY1911

Since I don't want to go with the 460 Rowland because of the compensator, how about going with the 40 Super?
I've been reading that the 40 Super is a hotter round than the 10mm. If you can get better than 10mm power out of a 45 ACP 1911 with just a barrel change, why not go that way if you reload? You get the option of using both 45ACP or bettering 10mm out of the same pistol. I know the chances of finding 40 Super in a Wally World are non-existent. Please note that this isn't a challenge. I'm trying to figure out the same thing the original poster is.

Swap out your recoil spring for a 28-lb Wolff recoil spring, put in a buffer (if your gun will run reliably with a buffer) and you can shoot .45 Super. You use standard .45 ACP cases and you can drive a 230 grain bullet to 1,100 fps, or a 185 grain bullet to 1300 fps. And it will still shoot standard .45 ACP loads with no modification. If you want to shoot light .45 ACP loads, all you have to do is go back to your old 16-lb recoil spring.

how about the 400 CorBon? Don't know much about it. Most of the reading I've come across says it's a barrel and spring change to mimick the 10mm

The disadvantage to the .400 Corbon is that it's a bottle neck cartridge. If you do a lot of shooting, that's a pain, since you have to lube the cases and de-lube them after sizing.
