Also the .223 Gold Dots are not hollow points but are soft points. Small detail but I thought I'd clarify it for the sake of providing accurate information. They feed in my AR very well btw, I've cycled a few hundred through.
The Importance of Hard Barrier Penetration

Come on Meke. You can't discount all of it. The Gold Dot still went through a windshield no matter what the angle. It still penetrated the gel consistent with the expansion based on velocity. From the 20 inch barrel it had more velocity, expanded more, and penetrated less than from the 11.5 inch barrel that had less velocity, less expansion, and more penetration due to the smaller expansion.
Those results are still consistent even if the gel is slightly off calibration giving results within a parameter of inches depending on temperature of the gel or an inch or 2 variance in windshield angle. All vehicles have variances in windshield angles.
The general idea on how the round behaves is still there within a parameter of a few inches give or take.

357 or 40 are My two choices for knockdown and hand control.

Lol. Within a parameter of a few inches give or take. I will edit it for those who may not understand.Parameter inches?

Will,
Those are decent rounds we already know that.
But come on man, my point is that the glass makes a HUGE difference more than other parameters.
The glass from a 70's car vs the 90s vs. a current car not just sports with large thick glass is not the same.
I think knowing the speed from a SBR is cool but what about shooting this with the tipical 16" AR from 50
and 100 yards. Give details of everything that is at play.
Put different angles and not a bare Gel but add some clothing, etc...
I mean this is better than nothing and given to the community but if one wants to really understand how
a round really behaves one needs to be more methodical and follow a process.
I know these experiments cost time and money and they offered to the community so we cannot really complain
but also keep in mind that if you really like a round do your own testing too.
For example the M855 is a great all around but you change angles and type of glass and the whole thing changes
just with the very small gap of air between the jacket and the penetrator that induces deflection in many instances.
This is someting that it was consdired a benefit when moving to the arrowhead design from Liberty amunitions.
Like I said many times auto glass is a bitch and working with different types and angles will show how a round
really behaves.
Those rounds are good rounds ... I am just saying....

The video would be 3 days long if you test for every different angle and at different ranges. Besides, you aren't going to have a shootout with a vehicle at 100 yards but that isn't the point. It's supposed to be a general idea.
He did shoot from 3 different barrel lengths.
In my opinion, popular ammo would be the first to go if shtf, and maybe the unpopular calibers would be left behind. Just my thought

I can stock up on popular ammo cheaply now though.
For example. I bought enough 9mm NATO surplus to last me a very long time for range sessions at 200 bucks per 1000 rounds.
Had I made .357 SIG my choice, I wouldn't be able to buy cheaply from my gun shop. Most of the time they don't have any and when they do, it's usually expensive defensive ammo. Online since there is no surplus, it would cost about double or triple what it would cost per round.
Give and take there. As Will said he is able to get it cheap now so he stocks up. Unprepared people are the only ones who suffer during a crisis, be it an ammo drought or a tornado.
During the last ammo crisis all the popular calibers flew off the shelf first (38,357, 9,45, 223,308,22LR, 270) you could still find .30-06, 300 Win Mag, 17 HMR, 22MAG, 40, 250 Savage and so on). One of my friends was asking about getting a rifle for hunting and target shooting. He wanted my opinion on caliber and brand. For caliber I told him if he wanted to be able to shoot it in the next 6 months to get a 30-06 because at that time you could still find it on the shelf. For brands and model I told him either Remington 700 or Savage 110.
After a while even the 22MAG and 17HMR guns were being sold since ammo was available and those calibers eventually dried up too. There is no guarantee on what is going to be available in the next crisis (there will be another one if history is our guide). My philosophy after getting a 17HMR when they first came out and not being able to get ammo for 6 months is: get 1500 rounds of the new caliber I am looking at before buying the gun.
