Underwood/ Lehigh Defense 10mm copper solids

Words of wisdom to be sure, and yes, collateral damage is the last thing you want. As for checking out the coyotes internal damage, I haven't done it either. I've shot a bunch of of them over the years, and they are one mange buggy critter : )

So...I am gonna say some stuff.  And I want to give it this preamble:  Be sure of your target and what is beyond always applies, even in defensive shooting. And I am not necessarily disagreeing with the words of others.

TrapperL6 has opined that one way to mitigate collateral damage is to try to choose load that does not have excessive penetration.  I have long held many internal debates on this subject.  Unless you are Officer John McClane and need to kill a bad guy by shooting through your own shoulder, it seems like good advice to stick to ammo that performs within the FBI protocol penetration profile of 12"-18".

There are some other realities to confront as well.  Typical defensive shootings yield a hit rates that very low, even at point blank range.  The NYPD keeps some of the best data on this topic.  This paper documents their data as well as data from some other departments.  The short version is at 6' and less, police can be expected to hit the target somewhere about 40% of the time.  A little better than 1 out of 3.  Keeping in mind the rule of three's in personal defense (three shots at three feet in three seconds), this means a police officer who trains and qualifies at least once a year will fire two shots that hit nothing.  And that third shot may or may not be center mass.  Even 10" of gel will result in lots of over-penetration in a shot that hits an arm.

A common response to this is that often a diligent citizen that concealed carries is trained as well or better than a LEO.  And that may be.  But, this study shows that the gap between a "novice" and a trained individual is only 10% when shooting at ranges under two yards under stress.

There are well and good reasons to stick with the FBI profile of 12"-18".  But considering that more than half the shots fired are likely to completely miss, I am not sure I agree that concern of a thru and thru shot is one of them.

Thanks sqlbullet, I have never been a licensed LEO, but did complete my bachelor's degree in criminal justice with an emphasis on information systems and security in 2014. It seems like they said 6 in 10 shots are missed, so yes, training training training is incredibly important
Thanks

Particularly where NY City has stupid trigger pull weight requirements!
Believe their police department side arms are required to have like 10lbs - 12lbs trigger pull weight and operating in double action mode (hammer fired pistols) only!

It's no wonder they can't hit anything and end up missing and hitting innocent bystanders with much too much regularity.

Sounds like the trigger on my Smith Bodyguard, just awful

Here is a video that proves the Xtreme Penetrator is no where close to a replacement for a hardcast flat point.

Agreed; there is ample evidence that definatively illustrates that someone needing 3 feet of penetration out of their 10mm, heavy hardcast is clearly the way to go. 
In addition to Andrew's new video...
5pins demonstrated that some time ago.
Kentucky Ballistics has illustrated also.

Now if someone was interested in deep penetration (but significantly less than 3') and wanted decent wounding outside of flesh directly touched by the bullet, Xtreme projectiles start to have their advantages.  Course from a cost perspective, hardcast gets the nod on much lower economic basis. 

5pins did some testing with a solid heavy copper projectile with a very flat face and large meplat surface which also penetrated like crazy similar to a hardcast.  But again for bang for your buck, when deepest penetration is what you require....  Hard to beat hardcast.
