380 short barrel Underwood Xtreme Defender vs Inceptor ARX 

Wonderful video. Been waiting, for years, for a no BS, no yak-yak, comparison of the "solid spinners" with conventional self defense 380 rounds........that INCLUDED energy levels. THIS IS IT !! Congratulations, guys............keep up the good work. [ have carried the ARX in my Taurus 738 for years......and now in my LCP Max. Feel quite confident with them, especially after these analyses ] ........and...........much less felt recoil..........

ARX wouldn't run thru my Ruger security 380. I tried 15 rounds and none even moved the slide back. I have ran over 20 different types of ammo with no issue! Underwood extreme defender worked great!

Nice comparison video. When I carry a 380 its an LCPII with the +P Underwood Extreme Defender. This test looks good for both non-expanding loads tested so I see no reson to change what I'm using.

Excellent Video....Thanks !! Looks to me like it's going to be Xtreme Defenders and Arx for my Sig P365-380

Something to add for you. Just did my own accuracy test between the ARX and the extreme defender, 7-10 yards. Out of my P365-380 both rounds group phenomenal but the ARX groups to the left of my point of aim. The Underwood is dead on with all my other range ammo. I think this is a big deal considering that your range ammo and your defense ammo should group relatively the same. Example, G-d forbid you get into a defense scenario you might have to double or triple tap in a hurry. That will usually result in a right handed shooter pulling to the left. If your defense ammo already hits to the left you may not get a good center mass shot, forget a head shot altogether!

The average male chest is 11.47" "thick." Therefore IMO setting 12" as the ideal penetration standard is a tradeoff with an array of probabilities. The FBI standard was sort of based on the worst case... shooting through the right side to hit the heart. Obviously there are a wide variety of tissues: bone, cartilages, muscle, blood vessels, organs, etc. Generally. the brain and the heart are lethal shots. Some others are leaks leading to significant blood loss. Since the brain is protected by bone, the better choice might be through the nose/eyes to hit the brain. There are targets that show all the organs, etc. Therefore the ideal training would be with those versus the traditional bullseye, etc. Realizing no matter where you get hit, it's going to hurt.

There is noticeable less recoil in the ARX imo, I just shot both today.

I have some of the ARX and extreme defenders. The extreme defender + p is my 380 carry round in 380. Federal HST + p in 9 mm.

Hollow point and fluted are equally effective, IF the HP changes shape, as intended. Sometimes they don't. Fluted doesn't have to change.

Those nice wound channels sort of look the same. Pretty cool. Underwood, I mean.

Excellent review and explanation! Well worth the time. I especially applaud the comparison of organic gel versus "clear ballistic gel!" Organic gel is the one to better show the wound track, and for what it is worth, shooting in the shade really works better to see it, and you took the time for us to really look at those wound damages. To my eye the Underwood did better! And the velocity of the Sig ammo was typically disappointing! Very useful test!..............................elsullo

I carry the Xtreme Defenders in my P3AT. They're worth the extra price to me for the additional energy and because I'm not going to cheap out on my defensive ammo. I'd also be curious to see how the polymer/copper Inceptors hold up against hard barriers like wood and steel. The XDs perform very well even after passing through windshields (it's realistic that an attacker may try to hit me or someone else with a car).

What is the felt recoil like, on these two rounds, compared with heavier (e.g. 95 to 99 grain) 380 defensive rounds?

Nice video! Love it. And 9 pumps works for me

Great comparison

Interesting tests. However, from prior videos on the .380, it's my understanding that Underwood's Xtreme Penetrator is the best performer. The XD's are better for 9mm, but for .380, the XP's seem to be better because a .380 needs a bit more oomph.

My friend, 380 is my primary. Federal HST gold dots, federal hydro Shack anhydroshock yourself deep, Buffalo bore. All of them go 12 in and expand every time

Less recoil with lighter weight ammo? Ruger vs Glock

This is a great test because it shows the Clear gel is not real, but your homemade is lilke the FBI gel, more flid like human flesh. More expensive showing the 380 ACP is adequate. Unederwood Xtreme Defender is best & adequate. 9 is better if one can hide it. LCP Max: adequate & better than not carrying.

👍

Their is a severe difference in cost. Copper bullets that have to be cut on a C&C machine are much more expensive than a bullet that is made through injection molding polymer and copper particles. Great test.

THOSE ROUNDS Will STOP A PERSoN for sure///....380 cal will not put you in jail plus good defense round
