I still don't understand the benefits of the 9x25. Why not just shoot the 10mm? I understand it's moving faster, but it's a smaller bullet. It takes more than speed to make big power, that being mass. Mass is lost, but speed is gained in a 9x25. A 10 is bigger mass, slower speed. Where's the trade off?

It's .357 Magnum power without buying a Coonan in an auto. Reports say the recoil is less but it's just another neat thing really.

But a 10mm is = a .41 mag?

If it's just something to tinker with, I guess I get that. It does haul ass!

Sorry, NOT = to a .41 Mag.  You can't get there from here.  Not even....  .41 will push a 220 gr. slug, easily, faster than the 10 can lob a 180.  My .41 does 1400 FPS with a 220 gr. Speer SJSP.  This is a moderate (target) round.  They were a LOT faster, before Alliant took away the playground (Blue Dot).  A light (as in, store bought) round is about 780 FPE, compared to the 10mm benchmark Norma load, at 639 FPE.  They're as different as Colt is to Glock.

I've heard that a million times! Sad that it's not true. So, the 10mm is less powerfull than the 9x25?

I thought Underwood's 200gr XTP's were flyin' @ 1250. Is this not true?

Their .41 210gr XTP's scoot at 1560.

You can get 135gr 10mm around 1600fps, and the guy in the video was talking about the 9x25's goin 1700fps, but they were lighter.

Not necessarily.  It can be, if you like tiny bullets.  However, you can have similar power with less recoil.  It's a wildcat, and it has its niche.  I don't load/shoot them, but will soon.  It's on the list.  Wildcats are fun, and they justify themselves.  I have a thing for "boutique" cartridges.  At the least, they add to the versatility of the 10mm platform pistol.

My above 220's are a moderate/target round, as said.  I load them a lot faster for anything serious (like elephant, stopping trains, etc.).  My (former) hunting round was a 220 gr. JFP at about 1600.  Underwood's round is no slouch, and I load some at about that (for HD--don't want to blow out ALL the windows).  My current hunting round (under protest) is the Barnes XPB 180 gr. at 1660 (1100+ FPE).  They would be better, but no Blue Dot.  I could really heat 'em up, but I don't push it to the edge.  BTW, these are all 75+ yd. accurate.  Worthless, otherwise.

There are two real applications for 9X25. One is it's original purpose of easily making major in 9mm in IPSC + having lots of gas to drive a compensator.  It did this very well, but the 40 S&W made major and wasn't a highly specialized round and didn't have the huge muzzle blast.

Second, it shoots light bullets VERY flat.  This makes it a great handgun varmint round.  A 90 or 95 grain JHP from a 6" barrel will really reach out there and take coyote or jack rabbit.

The smaller 9mm bullets can also be cheaper to shoot from the speed demon!   I like this little devil!
Yes, I already load for it, why it is different!  Unique!
The right bullets can really penetrate some hard targets including steel.
I even shoot cast bullets from mine.

1) flatter shooting
2) better bullet sectional density compared to the parent cartridge in the same or similar bullet weight (important for high speed bullets)
3) questionable, but more controlled recoil

...... 4) Because we can.
