Cleatus Van Damne: 10mm and .45 Super make me all happy face.
SickAudi: can't wait till they're' back in stock!! 200 grain JHP and the 220 hard
Stefano Dogg: The 135 grain Nosler load is a far better choice for civilian self defense
against bipedal hyenas. Underwood just restocked, I bought 6 boxes of the
aforementioned for street carry, and a buddy of mine and are loading the
same load for practice and zombie apocalypse ammo. You do great tests, but
please use the clear gel if possible in the future, it's awesome to see
that slow speed footage..
EABOY2600: This would make a great self-defense round especially if you have to shoot
the a car door or window, it's heavy but very fast it will punch through!
Bogs Craig: so, which one is the best hand carry self defence gun?
KevinJohn556: Looks awesome how ever living in a big city I would say overkill for me
unless I was hiking but that's what my ak pistol and hot 357 sig underwood
noel hernandez: Anyone ever test Underwoods .223 or. 556??
jeremy beverly: I've been looking to see if you've done a 40 in underwood but I can't find
it I want a hot load but Speer gold dot 165 has done me well. If you do
have a 40 underwood video can you guide me to it great video and thank you.
Jim Nesta: It looks as if Underwood is driving the XTP bullet beyond its design speeds
and causing excessive expansion and fragmentation. I would love to see the
XTP bullet in a full-power 10mm load with more limited expansion and more
Barry Newman: it is a crap shoot but it seems to be whos crap you like better. Massive
100REALM: I think the greater "energy dump" would equate to more knock down power
versus less energy & more penetration.
vegasbob007: Good video .Thanks .
Jim Nesta: The terminal ballistics of this round look similar to the performance of
the .45 acp +p 200 & 230 gr. XTP Hornady loads. Aside from the benefit of
greater ammo capacity in the G20 vs a .45 1911, I can't see a compelling
improvement in terminal ballistic performance in the 10mm G20 vs the .45
acp +p 1911. The greater kinetic energy of the 10mm here may be producing a
larger temporary cavity, but not much more in the way of an effective
wounding effect - the permanent cavity. My belief is that we have yet to
see an expanding bullet that has been optimized to convert the kinetic
energy of the 10mm into more extensive destruction of tissue in the target.
JayzBeerz: I still prefer .45 ACP Federal HST.
ediot6969: I have a glock 20c but I got a kkm 6" barrel and my velocity was 100 fps
faster than what Got in this testing which means anything from human to a
1500 lb bear is going down easy.
dhamilton201: in response to E.W.E. Hughes Jr. and Bob Cobb
I will have to second what Bob says ....You really dont have a
MarvelousSeven: This is really the only 10mm JHP brand I buy any more.
blackwerk: @ me2ontube imagine that small bullet weighing 706 pounds. now simply lay
that small 706 pound bullet on your chest. The weight of that very small
but now extremely heavy bullet will penetrate your chest from the weight
alone 706 ft/lbs of energy. hope this helps...
Jeff Gibson: Thats pretty darn impressive in my opinion. Considering an animals chest
cavity contains lungs filled with air, I believe you would get a complete
pass through on a deer. Just my thoughts.
Charles Marshall: To me there is no doubt that I will carry my 18 shot 9mm EAA Witness with
Underwood 147 grain loads. Much faster and more controllable follow up
shots that any other personal defense load out there. I've learned over
the years that a controllable pistol with plenty of ammo is best.
MrZacfisher: theres no way that bullet would pass through that block, all those jugs of
water, and on the other side of that theres trees...
tnoutdoors9: Probably 180 gr.
12799MaDeuce: Would make a good winter carry load
savagejo6661: Sorry, that's a Weatherby PA-459......THANKS!!!
RockGIV: Hey TN just thought I should let you know that I bought a box of .40 S&W a
couple months ago, but when I recently went to test it out I found that
inside the box that was marked .40 S&W +P there was 10mm!! and it didn't
even have gold dot bullets in the rounds! I have tried to contact Underwood
but they are expieriencing a "high volume of calls" and have gotten back to
me yet. No need to say I am now kind of worried about thier Quality Control.
mrwangchung: Underwood loads some good stuff, it's my carry ammo.
E.W.E. Hughes Jr: IMO the 10 MM round seems to be a tweener that doesn't really do any one
thing well. The .40 or .357 SIG is more than adequate for self defense, and
.44 Magnum seems like it's a better hunting round. 10 MM seem relegated to
KYpatriotism: I'm not trying to take away from you tnoutdoors, but in my opinion I
usually hunt medium game, white tail deer hogs, with a .260. I know of many
people who use a .223 which is sufficient to. Remember the size and power
of a bullet is usually never the complete and main factor in taking game It
almost always has to coincide with bullet placement unless you were using a
.50 BMG or similar cartridge in which you shoot it in the leg and it takes
its shoulder off. But the lowest I would use is a .223
JONYAG07: the .38 special is also shorter than the .357 Mag yet u can fire a 38 in a
revolver chambered for .38 Special... The problem is not firing the bullet
into the chamber, but firing a cartridge that is not headspacing (It can't
reach the chamber's shoulder)- simply held in place by the extractor.
MagicCat3: Energy Dump (adj.) To expel all of ones energy at once in a single
quantified location. Thus having the bullet not leave the body cavity.
Bill Kunert: Have you done gel test using win white box. 40 180gr jhp?
chopinbloc: Sure. Once. I'm kidding, of course. People have done it but it's not a good
idea because the cartridge headspaces on the case mouth.
KYpatriotism: This might be hard to believe but my local outdoor and firearms store had
the cheapest price for all and any ammo anywhere I've been including the
internet until the introduction of gun control legislation, it is still
inflated but only slightly above internet prices and much cheaper than
other local places. It is still cheaper to buy from their if you factor in
the shipping you would incur on the internet unless I was buying thousands
rounds in bulk. I'm usually a weekly ammo buyer..
eromusofwom: Huh? Every bullet is designed to kill. A .45 ACP bullet at slower
velocities will actually expand to a wider diameter and potentially cause
even more damage to vital organs. What do you base this ridiculous opinion
jigsaw183 .: Thank goodness you are back up and running. Your videos are awesome.
GarnetGoldGunner: TN!! Get your hands on some Black Talons!
Hernandez048: What do you guys hunt with a 10mm? Other than things that bump in the night
Ohio10mmFan: Thanks for another great 10mm test. I load this bullet to 1150 fps over
some Longshot as a deer/medium game load. After seeing your test I think
this would work and would now consider it for HD use as well. I am planning
on pulling some 180gr Ranger T Bonded bullets for load development for the
10mm. We'll see how that works out.
MrWhitetailtracker: Well a BB could to if it hit you right but let's be realistic Tiggerman323
xtremearmor: Outstanding video. The bullet had very nice expansion and the penetration
was spot on too. You brought up some very interesting points about the
velocity of this ammo too. Very well done!
fivefoflow: Who said anything about hunting?
David T: I've been watching your videos for a while and I think they're great! I
think we'd enjoy seeing a 155 gr all copper barnes loaded in 10mm by
buffalo bore. Please throw that bad boy into some sim test.
chopinbloc: No it's not. Not even close. It's roughly equal to .357 mag in terms of
energy. 10mm can push the heavier bullets just a little faster than .357
can push the same bullets. 10mm is well short of .41 mag and this rumor
needs to die. Anyone with double digit IQ and just barely literate can pick
up a reloading manual and see that 10mm is nowhere near .41 mag.
MrWhitetailtracker: This would put a bad guy on the carpet in a hurry.
W. Tinnen: Ha ha ha, and A LOT lighter than a shotgun! I'll look in to that bear spray
again then (it has been a couple years since I've checked them out). Yes,
the 2 legged threats. You've given me some good ideas--bear spray and a
Glock; but something smaller, like a 26. I can leave Mossy at home. Thanks
mememojo: can 10mm be called .40s&w magnum
Luis Postgate: To bad the government plans to take all of this away from us
Southern Shooter 86: Federal 9BPLE.....
Oh Kay: Every bullet is designed to kill. However, wound channel size is so similar
between the .45 and the 10mm (10mm is a super hot .40SW), that the next
factor is power. The 10mm is dumping massive FT-LBS of power into the
target. There will be more surrounding tissue damage and collapsed
tissue/veins/artery from the pressure than the .45. I love both, I carry
either an XDm .45 or a G20SF
dragonballjiujitsu: I would never consider this load for self defense. This is a good hunting
load for black bear or deer maybe but way too much penetration for street.
My comfort zone as you say is around 9-10". Anything more is going to zip
right through the human body and kill who ever is behind them.
EMT: Thanks! They sometimes skip corners and take the easy way. If they ever did that, I suggest you consult with a paralegal or lawyer. This way they won't be able to cheat you.
