If anyone has tried it, what did you think of it?
This video is 5 years old but the information is likely still valid.
Looks like Underwood achieved their advertised velocity of 1300 fps. Righteous.
The 124 grain load is certainly a better choice than Underwood's 115 grain +P+ loading that uses the Speer Gold Dot.
Underwood promises 1400 fps from a 4" barrel. tnoutdoors clocked a 5 shot average of 1434 fps from a 4" barrel. Wow.
So, Para, why do you say the 124 grain offering is preferable?
One word: penetration
The extreme velocity of Underwood's 115 grain load means that it expands to an incredible degree (.880" in the video), but it penetrated to 9 inches only, as opposed to the much more desirable 13.25 inch penetration of the 124 grain load.
The accepted standard for self defense ammunition is 12 to 18 inches in ballistic gelatin. The 124 grain load fails within this window. The 115 grain load does not.

Well Duh! I should have thought about YouTube.
I've tried the non bonded Nosler bullet version and it's not bad recoil wise and it's accurate.
I need to get some more one day, too bad he switched to only selling the 20 round boxes over the 50's.
If breathing wasn't automatic, they'd be too stupid to do it.
I chronographed it from my Sig P228 at just over 500 lb-ft of kinetic energy! It's a seriously potent SD load, and far superior to most of the crap being "marketeered" as SD ammo while producing 330 lb-ft of KE.
I tested the 124+p+ gold dot as well as the 115+p+ from Underwood. I used my Glock 19 for both. Fired from 10 feet into Clear Ballistics blocks covered by a layer of 14oz denim,a sweatshirt and a heavy t shirt I got the following.
124+p+ 15.0 inches expanded to .64x.46 for avg .55
115+p+ 12.5innches expanded to .696x.52 avg is .61
115+p+ was gold dot also
Kinetic energy isn't the whole picture, and a round that doesn't penetrate (115 gn, as noted above) can hit hard, but still not have the terminal effect desired). Pushing +P+ to get that hit, or to push performance, isn't necessary, and falls outside of known or set standards for safety. There's no need.
If there's that much need to push pressure, why not go to a different cartridge?
Do you have pictures? Also, you didn't want to try the 147gr? In the Tnoutdoors9 tests, that did spectacularly.
