Bill Wilson was so impressed with Leighi Defense performance he bought the company and he is on record as carrying in his 9mm Leighi Defense
I’m sure if Winchester ammo was a small company available for purchase within Wilson’s means, and Wilson thought it would do well under his umbrella, he’d be carrying RA9T, and telling us that he does. He certainly wouldn’t say “well, I bought Winchester, but I’m really more impressed with Gold Dots, but Speer wasn’t selling. So I sell Winchester, but carry Speer.”
Weird. A common theme is that .38, .357 mag, and 9x19 124 / 125 gr bullets that expand well are marginal on penetration or slip sideways and / or get deflected off a straight path. So many variables though.
I don’t know for sure, but I think he was impressed with the hunting rounds by Leighi and that sparked his interest. The pistol rounds just came with the company. Leighi make multiple styles of handgun ammo and he carried the fluted rounds, because they work.
I think the fluted rounds are better than traditional ammo for the following reasons. First they are barrier blind, second they have no cavity to kill up with material so the round becomes like a ball round. I then think in the 357sig round with the over 2000fps speed they will do rifle like damage.
They sell a few brands.

Best I can recall from 20 years ago they were selling.45 ACP using VV N320 for low flash and decent velocity with a Speer 200gr, but can’t recall if it was the ash tray or gold dot.
“Ash Tray” and you’re dating yourself. 
That’s going back a ways, and yeah- I shot them.
I don’t see where they’ve been tested at those speeds, and Lehigh doesn’t list them as a rifle/carbine bullet. The do have an extensive line of rifle bullets too of course. The 357 Legend has its own design, so no overlap there. Has this design been tested within FBI protocols at the velocities you’re anticipating? I didn’t see anything on YouTube either. I’m not bashing, just asking. It seems to be an omission on their part, or maybe I just didn’t find what I was looking for.
Bullet construction is infinitely more important than weight.
We do need more testing with these bullets at higher velocities.
I did see some testing vs armor.
I wish I could test these myself but I don’t have the facilities. I rely on the Underwood-loaded 68 gr Lehigh bullet in three guns. 9mm pistol (1710 fps), 9mm carbine (2120 fps) and .380 (1405 fps). These numbers are from my chronograph best I can recall at the moment.
Now that Lehigh has some serious money behind them some of these gaps can be closed. IIRC, they’ve been passed around a bit in the past by investors. Perhaps now things can get serious.
Guys I found the new prototype Leigh Defense projectiles they are developing.
But seriously, I wouldnt be jumping ship from JHPs to Lehigh projectiles unless I see some large dept OIS data or autopsy data correlated with lab testing, even something like being backed by professionals like DocGKR would be decent, as far as I know there is nothing but hearsay in terms of real world performance from their bullets.
C’mon, man, thats not true. Be fair. There is also hype and misinfo.
I have seen the damage it does on flesh, but not human. It works great Bill Wilson also talks about shooting hogs with it.
The late Jim Cirillo talked about rounds above 1900fps work different than pistol velocity rounds.
When it comes to the 65 grain 357 sig, I have no doubt it will work better than any regular pistol round. It is hitting at the same velocity as an AK or SBR AR
There are many of videos of these bullets doing JHP-like damage to meat and gelatin. With more consistent performance than JHP’s.
But not from rifles.
Check this one out. Start at 4:30. https://m.youtube.com/watch?v=FWgXc9L9vx0
I think the lightweight Lehigh pistol bullets do as much damage as an expanded hollow point with fewer drawbacks (can’t clog, don’t have to expand) with additional benefits. (Lighter gun, less recoil, barrier blind, won’t break up, can penetrate some armor, less likely to over penetrate)
I do think they aren’t as desirable at longer ranges (50 yds?) Because being light they will lose momentum faster than a heavier bullet and may not penetrate enough.
It’s interesting how some people who quickly accepted red dot optics on pistols are very skeptical on new-tech bullets.
124gr +P GDHP is what I carry, and it works well on my Glocks and Sigs handguns.
I like Gold Dots 147gr and Federal HST 147gr too.
Its a function of how receptive we are to marketing vs other definitions of performance.
I watched it, even Andrew agrees at the 9:00 “while it looks cool it doesnt really prove anything” https://youtu.be/FWgXc9L9vx0?t=543
The video conclusion’s is that its still a big question mark whether this wounding mechanism actually translates to real world performance. Im not sure how this relates to red dots on pistols, red dots pistols have been around for almost 2 decades in the competition world, and they only hit the main stream about 5 years ago?
Im pretty open minded to new tech if there is sufficient data to back something up, but there isnt in this case. Remember 4.6mm and Five-Seven also produce pretty dramatic temporary stretch cavities and no one is writing home about their spectacular real world performance.
I’ve attended a considerable number of autopsies and seen the end result of handgun ammunition on human flesh. When it comes to ammunition, I want to know how it performs in the field. I don’t care about temporary wound cavity, bullet weight or bullet velocity. I want to know the track record of the cartridge. The key question is “how fast did the violent attacker stop after being shot with the cartridge?” You cannot collect that data on the autopsy table or from the medical community. It has to come from people who use the ammunition in a fight and competent witnesses.
Once a significant amount of real-world data is collected, I’ll consider a cartridge for defensive carry. Time will tell if Mr. Wilson’s LeHigh cartridge is a fight stopper.
I’m only mildly interested in the stretch cavity performance of the Lehigh bullet.
If it cuts a hole as well as a jhp but does so while possessing the other advantages it has that’s good enough for me.
