9mm Bullet performance

"Seems" isn't supported by valid and verifiable data.

This is where someone brings up Marshal and Sanow's average incapacitation time "data"

Comparing inches of penetration and milimeters of expansion is fun and all, but just about every modern 9mm load will penetrate deep enough to reach the vital organs of the average human.
Penetration is seldom the problem with the 9mm.

That's only if you are considering frontal COM shots. Remember that gel represents an average penetration through a human. There are going to be some that underpenetrate and some that overpenetrate. If you read the link my previous post, you'll see that some of the 147gr bullets penetrated only 10". 115/124gr bullets would have penetrated even less, as they average about 20% less than the 147. I would be uncomfortable with a load whose penetration ranges from 8 to 16. A 10-18" load is better IMHO.

People seem to place more importance on bullet weight when estimating penetration when the powder charge and actual physical design of the bullet are more important variables of penetration.

Some folks will not believe that they're standing in a rainstorm unless the weatherman confirms it with "verifiable data".

Just shoot 9mm FMJ, of about any weight, and you should easily get that kind of penetration in the average human.

But as I stated earlier, there's more to stopping a human than bullet penetration.

You got evidence to share or just more unsupported opinion?

I prefer the Hornady CD I dont want over penetration you should check with your state laws remember if you actually ever have to shoot, your responsible for that bullet from the time it leaves your gun until the time it stops. Your also only allowed to shoot until the threat is stopped. If he runs or drives away and you shoot through his car door your most likely going to jail, maybe for a long time. You need to pay a little more creed to the state and federal laws and less to FBI bullet penetration ratings.

Actually, you are allowed to use deadly force to make a felony arrest in most states.

Not this time, as this thread is about 147 gr specific bullet improvement/performance.

AIT and ballistic pressure wave/hydrostatic shock is more relevant to 1200-1300+ fps generated by lighter/faster 115-124 gr bullets compared to sub 1000 fps generated by heavier 147 gr bullets.

However, I am happy to see enhancements being made to all calibers and bullet weights. More ammunition choices for us consumers, the better.

This allowance has been lessened by the supreme court case Tennessee v Garner. In a nutshell you can use deadly force to stop a fleeing felon, but only if he is a clear and present danger to society if he gets away (terrorist, serial killer, active shooter). Even so, it is still frowned upon. If a citizen were to shoot a fleeing felon you can bet that person will catch all kinds of hell.

For those who might be interested in discussing the use of deadly force in felony situations, you can start a thread about it in the Strategies and Tactics sub-forum. Let try to stay on point here.

Thanks

Sidenote: this thread had more life in it than I thought, especially when you considered that I pruned it from a necro thread

Good job Dr. Frankenstein.
