Some Mysteries Are Too Deep..........

Like This One:   Hornaday Critical Defense Rounds

They pre-plug up the hollow-point with red plastic so that it won't get post-plugged up with blue denim.


I guess it's all right.

Just Thinkin'..........

I think it was originally for use in those old-fangled 1911s to help feeding.   ;D

Just for you.  The pre plugging works well at keeping it from pluggin...

Mister Doctor PhD Physics Professor (aka SFG).....don't you realize that the bullet is moving so fast the plastic melts on its way down range and at the right moment (and ONLY the right moment) said plastic complete obliterated at the point of contact with the target thus ensuring proper entry and subsequent expansion...... or so it sounds good made up ....

The funny thing about these is for every internet page of a guy getting great expansion as he shoots (take your pick: milk jugs, dead animals, ballistic gel, pumpkins, mud), there's another one who gets no expansion. 

None of which means anything scientifically, except for the fact that I never seem to see quite as many negative reviews of some other "premium" projectiles, e.g. Gold Dots.  Might just be the calibers I'm reading about, though.

Now there wuz this story of the Perfect Crime, where the Perp shot bullets made of dry ice, which then evaporated and left no trace of the murder weapon.

Does not work on victims wearing Blue Denim.

It's not just red plastic, it's tactical red plastic. 

No mysteries here.

It's commonly known among physicists (BTW-I'm actually a mere chalk-on-the-butt engineering professor, not one of those lofty high-IQ physicists) that moving objects grow in size as they approach the speed of light.

Which means that if you had sufficient velocity, you could pack a 9mm, but it would hit with the impact of a .45ACP.   And you wouldn't have to lug around all that metal.

Let's give unfy some hot powder and turn him loose on this project.

First the regrettable experimentation with the .40S&W round, now the desire for a 9mm rail-gun round? 

Is this seeming breach of loyalty to your beloved .357SIG round a subtle cry for help or indicative of  the onset of a mid-life crisis?  ;D

So Many Issues Raised Here; So Many Hidden Layers Now Exposed.

First, we have needed Someone to head the Forum Ministry of Culture.  RedDot is a shoo-in.  He has the rare gift of flash insight into the very heart of things.  Give him just a few bits of seemingly unrelated information, and Voila!......... It's all neatly laid out.

Second, I've been low-profiling the .357Sig thing lately.  Perps hear about its Wonders, they may all rush out and get one.  Just let them lug around their 9mms for now.

Third, the .22Calibri Mousegun Railgun will break out from concept to development as soon as the NRA comes up with funding.

Fourth, my midlife crisis was..........so long ago.   sfg has weathered that event with only minimal scarring and is now running fast on the far side.   Hard to believe, really.   You'll see when you get there.

There's more, but I shouldn't want to drone on.   Few things worse than a gun bore.

New indoor range opened in Sioux City Iowa, I got a first day open tour, the backstop is angled steel covered with ground up tire many inches thick.

About half way down the 75 foot range on the floor were the bullets from Hornady Critical Defense 380 ammunition, it could not penetrate ground up tire and bounced back, there was no expansion just the tip of the bullet pinches shut around the plastic insert.  This is what I found about Hornady XTP bullets years ago, no expansion just a pinched shut hollowpoint.

I'll keep that in mind if I'm ever attacked by an assailant armored in several inches of vulcanized rubber crumbs .....

Shot into water, bowling pins,  moist earth, or wet newsprint/phonebooks, or even wet snow .... most any hollow point I've ever used has expanded and imparted better energy on target than any fmj .....

Obviously you've never seen how ugly it can get when the Michelin Man gets his drink on. :o

On another note, a buddy of mine just came home with some of the G2 R.I.P. ammo in 9mm.  At $47.50 for a box of 20 it had damn well better be "the last round you'll ever need" as a warning shot would just be financially irresponsible.

After viewing the ballistic test video on their website, I had a question.  It would appear after penetration, separation, and immediately following the collapse of the hydrostatic shock-wave, that a small secondary charge goes off in the gel.  Is this an explosive round or am I just seeing the effect of other factors inside the gel block?

Not explosive. Just fragmentation with different size fragments.

I have seen it before.   What you are seeing is the largest fragment continuing to advance after the smaller fragments have stopped.
