I keep seeing videos that compare 10mm to 357. What gives, 44 mag is closer to 10mm than 357. 41 mag would be the closest, is this to just push gun sales.
357 Mag and 10mm Auto compare nicely. Both run a bit over 700 ft-lbs when push to max pressure with heavy for caliber bullets. The both fall well short of 41 Mag and 44 Mag. 41 Mag can exceed 1000 ft-lbs and 44 Mag can easily exceed 1200 ft-lbs of energy.
They are comparing a 9mm class gun to a 10mm class gun and most often say the 10mm is better. Compare 10 to 41 and then extol the vertue of additional rounds. Its marketing just like the 350 legend compared to the 30 30.Agree completely. Any comparison between 10mm and 41 or 44 would be more about the platform and capacity rather than ballistics - both are at a different level than 10mm from a ballistics standpoint.
It seems that you are comparing the diameter of the bullet rather than the actual performance. I'm a huge 10mm fan but I'm also a realist. 10mm is roughly equivalent in power to .357 and that's just how it is.They are comparing a 9mm class gun to a 10mm class gun and most often say the 10mm is better.

Correct I believe in comparing like things.It seems that you are comparing the diameter of the bullet rather than the actual performance. I'm a huge 10mm fan but I'm also a realist. 10mm is roughly equivalent in power to .357 and that's just how it is.
Similarity in diameter is not the appropriate grouping at all..Correct I believe in comparing like things
The physics says the larger diameter always has the advantage. Range can equalize but then sectional density being equal would be more fair. The concept is ten is as good or better than .357 where the idea should be its significantly reduced for caliber when compared to equal magnums.Similarity in diameter is not the appropriate grouping at all..
No.The physics says the larger diameter always has the advantage. Range can equalize but then sectional density being equal would be more fair. The concept is ten is as good or better than .357 where the idea should be its significantly reduced for caliber when compared to equal magnums.
Really, the larger diameter at near or equal pressure.No.
Physics does not address diameter at all. The larger diameter does not always have the advantage. Compare a .38 Spl with a .41 Short Colt
"Magnum" is a marketing appellation.
Well, just maybe, but those are things underlying.Really, the larger diameter at near or equal pressure.
Exactly.They are comparing a 9mm class gun to a 10mm class gun and most often say the 10mm is better. Compare 10 to 41 and then extol the vertue of additional rounds. Its marketing just like the 350 legend compared to the 30 30.
Comparing 10mm (.400" projectile) to .41Magnum (.409" projectile) leaves the 10mm looking kind of sickly and pale. But, comparing it to a .357Magnum (.357" projectile) makes the 10mm look pretty good... mostly.357 Mag and 10mm Auto compare nicely. Both run a bit over 700 ft-lbs when push to max pressure with heavy for caliber bullets. The both fall well short of 41 Mag and 44 Mag. 41 Mag can exceed 1000 ft-lbs and 44 Mag can easily exceed 1200 ft-lbs of energy.

The wild card that is often over looked is barrel length. Published ballistics numbers for magnum revolvers are from 7- 8" test barrels, which almost no one uses. Published ballistics numbers for semi auto rounds are from 4.5-5" barrels. In the real world most semi's actually have 4.5-5" barrels and real guns actually match those published numbers. The 357, 41, and 44 magnums are in another class as long as they are fired from long barrels, but are significantly slower from 3-4" barrels. Even from 6" barrels they are noticeably below published numbers.
Most magnum revolvers in the real world are 3"-6" in length. And when you compare the overall length of a 4.5" semi, it is almost identical to a 3" magnum revolver and actually smaller than a 4" magnum revolver. When 357 mag is fired from a 4" barrel it is a ballistic twin to 10mm. A 41 mag is only a tiny bit more potent and a 44 mag is closer than most people realize when you start shooting them in guns of comparable overall size.
So yes, any of the magnum revolver rounds will out perform 10mm. But if I need a 7-8" barreled handgun to do it, I'd just as soon carry a short barreled rifle.
So now your comparing rifle to pistol. Apples to tanks comparatively. I see we need cradle to grave explanations for some.Larger diameter always has an advantage? So 10mm Auto is better than 308 Winchester?
The 357 and the 10mm are compared because they shoot similar weight bullets at similar velocities. The difference between a .357 bullet and a .400 bullet is less that 1/20th of an inch, or about 1 mm.
