EFMJ

[Rastus]

If in doubt remember, .45's never shrink ! 

Kmitch200...it would be interesting to know what calibers failed. 

Tom is right.  Carrying my M&P in 45 on my long trip to Louisiana.  Maybe another thing or two as well...can you say Bushmaster?

I tested the 200gr .45 acp+P out of a SIG220 (4.40").  Would they have done better out of my 5" 1911?  I don't know.

The download 2008 Federal catalog doesn't list this load. They have the 165gr @ 1140fps. Perhaps the 165 has a better track record if they have any track record at all. 

The catalog states the EFMJ is "An ideal choice for agencies that don't permit hollow point ammunition."
I am under no such constraints.

In reality, not as important as we make it. 
In the patients I've treated and the autopsies I've seen, WHAT got hit is a damn sight more important that what it got hit WITH.
From 'Dead Right There' due to a puny .25 FMJ or talking all the way to the hospital with parts of liver hanging out from the contact shotgun blast.

Yours may have expanded in testing - some of mine didn't, and penetrated like a +P FMJ. I didn't even get through the box before I gave them the thumbs down.   
A few looked like I could have reloaded them.

The do or die test? Four layers of t-shirt material in front of 2 one gal water jugs. (The EFMJs that didn't even wrinkle needed more than 2 jugs for recovery.)
^{And it means diddly squat unless you are attacked by water jugs wearing t-shirts.}

That test is the reason I use mid to full weight Gold Dots.  They failed the LEAST often by far.

Hit something VITAL!!
Were you shooting the rubber ball rounds or the new lead ball insert? I think improvements have been made, as well as more weight in the round with the lead.
