    Way too light but I'd love to see a gel test. Probably about 8" of penetration but one hell of a cavity.

    :dunno:

    The same Xtreme Defender bullet (which is made by LeHigh) out of a 'weak' .380 ACP penetrates 14 inches.

    https://www.lehighdefense.com/products/380-auto-65gr-xtreme-defense-ammunition?variant=5863378564

    What makes you think that the same bullet out of a .357 SIG (with almost 1000 fps more) makes only 8 inches?

    On top of it, Underwood loads hotter than LeHigh.

    I say this round penetrates well over 20 inches in 10% gel with a comparable wound channel to a HP.

    Underwood states 18 inches penetration with 635 ft/lbs of energy, this round need a serious look.

    They have a 9x25 Dillon 90gr that does 2000/800. Got a couple boxes of this, just looking for something worthy to shoot.

    I'm always skeptical of really light for caliber offerings. Having shot some things with very light but fast rounds they just don't seem to hit with the same authority. Kind of like a flea running into an elephants ass. It doesn't really matter how fast its going, its just a tiny flea.

    Interesting that the 357 Magnum, 357 Sig, 9X25 Dillon and 10 mm now have modern effective ammo that reaches rifle velocities thanks to small select companies that are not afraid to offer new products. This in contrast to the larger ammo companies that are lowering ammo velocities and only developing new sales gimmicks. The world of guns and ammo is moving forward with new products and ideals. The big ammo companies are still trying to figure out how to make .22 ammo! If it were not for CCI and imports we would still have a .22 shortage and high prices.

    I don't doubt the Lehigh bullets penetrate, but I don't think they will work as advertised. I suspect the design of the bullet takes advantage of the properties of gel to show a hydraulic force that probably won't translate into increased wound diameter. I think they're mostly expensive CNC FMJ bullets with some fancy cuts on them and an expensive pricetag. Color me skeptical.

    What purpose does an extremely light bullet have except for possibly a few specialized applications?

    For purely self-defense I will stick to 125- through 150-grain bullets in .357sig.

    357 Magnum has been around for a long time.
    Lots of light to heavy rounds used on the street.
    125 gr at 1,450 fps seems like the sweet spot.
    Underwood 357 Sig is advertised at 1,475.
    But regularly exceeds 1,500 in actual chronograph tests.
    My Hk P2000 and Sig P229 should be very close to Magnum Force.
    High tech, street proven, bullets like Speer GDHP.
    Are icing on the cake.
    Call me Old School.
    But until I see proven street performance?
    I'm not buying in...

    Because of their different designs and functions it is difficult to compare Lehigh's
    terminal performance with that of traditional bullets except for the comparison of actual use in SD situations. However the interesting thing about this Underwood offering is pure and simple speed, rifle velocity out of a handgun the size of a G32! Even greater velocity out of a G31 or G22 with a 357 Sig barrel also consider the use of a 6 inch barrel in these guns. The estimated velocity for this round out of a 6 in. barrel is around 2300 fps with 765 ft./lbs. of energy! I have placed an order with Underwood for their 125gr Gold Dot and 65gr XD 357 Sig rounds I consider both to be valuable. For now the XD will be my anti barrier round until it is proven in other areas the Gold Dots will be carried.

    I would like to see this bullet next to a normal, 115-147 grain bullet. It seems that a bullet of .35 cal but only weighing 65 grains would be very short with very poor sectional density. I wonder how it'd fair versus bone.

    Have you tried any of their 300 grain brass bullets? Pretty nice.

    The bullet would not have good sectional density but since it is made of copper which is lighter than lead the length should still be good. There are a lot of unknowns about this round but what is known is Underwood gives a penetration depth of 17.5 inches in gel, it has more ft/lbs of energy (635 ft/lbs) than a 357 Magnum and at 2100 fps should have a hydrostatic shock value very near that of a rifle. If it were to hit a bone and tumble it should still have the bullet length and velocity needed to allow the tumble to do a good deal of damage. But the key to this rounds success should be its velocity and fast energy dump. I would not want to go hog hunting with it but limit its use to BG shooting.

    Makes sense, didn't even bother to think about the big difference in density and was trying to figure what the heck that bullet would look like. More ammo options is a good thing, always good to see manufacturers trying different things too.

    No I have not, I usually don't bother with fancy expensive machined bullets. Though I do want to try some of the 110gr aluminum CQB bullets sometime.

    That velocity out of a pistol (auto) is impressive. Hope to see some gel testing videos.

    Not only gel but some barrier tests are also in order for this speedster!
