Seems likely to me! "The math checks out" as they say. Of course that does not always translate in the real world, but makes perfect sense to me.

2000fps is 2000fps, physics are physics. Then if you add the flat front of the bullets, I think that alone would give good results. Then if we add in hydra junk science with the flutes it can hurt.
Then you look at the jello results it penetrates 17 to 18 inches.
The biggest question I have how much of a difference one might achieve between the 68 grain +p that out of a 4 inch test barrel goes 1800 out of a 5.5 inch barrel I am hoping for 1900fps V the .357 sig 65 grain at 2200 fps out of a 6 inch barrel.
A 68g bullet doing 2200 fps is essentially SBR AR numbers, with a different shaped projectile, so that sounds to me at least like a winner. I'd expect rifle type perm stretch cavity effects seen at the higher velocities. The jello vids of the bullets were impressive. That's why I had put up this thread a while back:

Some feel it seemed just an ad for Leighi Defense but I'm still really interested in that bullet.
Here is where I am going with this project, as of now.
1. I am on a waiting list for a Glock OEM 17L barrel once I get that I will run the 68 grain Leighi Defense through a chrono and see what it is.
2. I have changed my direction as to platform for now and I have ordered a KPOS Scout to fit the Glock
3. If the FPS are not enough out of a 6 inch barrel, meaning closing in close to 2000FPS. I have found a place in Europe that makes 7.5" Glock barrels. In one of the reviews at Underwood for the 90 grain 9mm +p+ which is rated out a 4.5 inch barrel by Underwood at 1550FPS, one guy says he is getting 1800 fps out of a 10 inch barrel. So if I can get the FPS I want out of the 6inch barrel, then I will go up to the 7.5".
I am now thinking a Glock in a KPOS with a brace, will give me greater flexibility than getting an AR or the B&T.
I know many people here think this bullet is a gimmick, but 2000fps is 2000fps and that if sBR rifle velocity.
A friend of mine talked me out from trying to do this project in 9mm. In .357 sig I will be over the 2100fps and not have to mess with buying different barrels. So the only purchase will be ammo and some more 40S&W mags.
How are the various size of ETS mags in 40S&W?
Don’t quote me on it because I have no experience with it.
But I read somewhere that the Roni (and perhaps the same with the KPOS and similar platforms) is not as accurate. The sights (or red dot) are on the Roni frame instead of directly on the slide (which moves with every shot), so the relation of the sights to the slide/barrel changes constantly.
Call me dumb, but wouldn't a 357 magnum NOT be able to work in a magazine?
That stupid rimmed case seems like it would really mess things up.
I agree, a 357 SIG could be fun.
I am slowly getting everything I need. It seems the country is falling apart and things are not available.
Due to this I am moving ahead with both 9mm and 357sig.
If I remember correctly someone makes a .357mag 1911
