An interesting article on Ballistics and testing
« on: June 25, 2012, 03:32:21 PM »
I found this on the Seecamp Forum and thought it was very interesting.

     http://ammo.ar15.com/project/Self_Defense_Ammo_FAQ/index.htm#PISTOL%20AMMUNITION

I found this Quote from the article on the auther's list of acceptable 9mm loads particularly interesting:

 "If you take all of these criteria into account, the lists should come as no surprise. Please note that all of the recommended pistol loads listed below have been personally tested and vetted by Dr. Roberts. THEY ARE NOT IN ORDER OF PERFORMANCE, SO ANY BULLET ON THE LIST IS CONSIDERED ACCEPTABLE.
 


9mm

Barnes XPB 115gr HP (35515) such as loaded by Cor-Bon (DPX09115)

Winchester Partition Gold 124gr JHP   (RA91P)

Winchester Ranger-T 124 gr +P JHP   (RA9124TP)

Winchester Ranger Bonded 124 gr +P JHP (RA9BA)
Winchester Ranger-T 127gr JHP +P+   (RA9TA)

Winchester Ranger-T 147gr JHP   (RA9T)

Winchester Bonded 147gr JHP   (RA9B/Q4364)

Speer Gold Dor 124gr JHP
Speer Gold Dot 124gr JHP +P   (53617)

Speer Gold Dot 147gr JHP   (53619)

Remington Golden Saber 124 gr +P JHP bonded (GSB9MMD)
Remington Golden Saber 147gr JHP (GS9MMC)

Federal Tactical 124gr JHP   (LE9T1)

Federal Tactical 135gr JHP +P   (LE9T5)

Federal HST 147gr JHP   (P9HST2)

Federal HST 124gr JHP +P (P9HST3)

 
You might notice that the list does NOT include any lightweight bullets with the exception of the Barnes 115gr version. The reason - especially if you've read the beginning of this article - should be clear already, but Doctor Roberts sums it up nicely as well: "With the exception of the Barnes 115 gr XPB all copper projectile, in general, most 9 mm 115 gr loads have demonstrated greater inconsistency, insufficient penetration, poor intermediate barrier capability, and failure to expand in denim testing than other 9mm bullets. For those individuals wanting to use lighter weight, supersonic 9 mmís, I think a better alternative than the vast majority of 115 gr loads is to use the slightly heavier 124 to 127 gr bullets or the Barnes 115 gr all copper bullet"

MRC,
Thanks for the link.  That's quite an article.  It will take me several days to read and absorb that much information.

I don't see any Hornady on the list.

Imagine that! It must be an omission.
