DISCLAIMER- THIS IS NOT A SCIENTIFIC TEST. I MIXED SOME GELATIN AND WATER IN A 1:9 RATIO AND SHOT IT. I JUST DECIDED TO SHARE MY EXPERIENCE WITH THIS ROUND, SO PLEASE, NO FLAMING.
Anyway, I was really impressed with this round. Shot from a 1:9 twist 16 inch Bushmaster AR-15 M4, the bullet penetrated roughly 16 inches of gelatin. I also discovered that the bullet is designed with an "A FRAME" jacket. At the approximate level of the cannelure, the jacket sections the bullet. Becuase of this, the bullet will always retain a certain amount of weight, will always have a controlled expanded diameter, and in my opinion, best of all, will always show significant fragmentation.
Like many of you already know, the main wounding potention of rifle calibers, especially the .223/5.56, is its fragmentation. Many bonded core, controlled expansion bullet maintain minimum fragmentation, and controlled expansion, and generally dont make a permanant cavity larger than the actual expanded diameter. While I think that these bullets would be more than sufficient as a self defense round, I really prefer some fragmentation, while acheiving a high retained weight, decent expanded diameter, and deep penetration.
This bullet seems to have the best of all worlds. Expansion was pretty early in the block, and fragmention was pretty significant. And most importantly, penetration was deep. The temporary cavity was very similar to Hornadys 55 grain VMAX I have tested, although many doubt the significance of that.
I am not claiming that this is the best round for any job, but after testing the following loads;
Hornady 55 grain VMax
Hornady 75 grain OTM
Winchester 64 grain PPP JSP
Remington 55 grain PSP
Winchester 45 grain JHP
WWB 55 grain FMJ
Guat 55 grain FMJ 5.56x45MM M193
I think that this load is a great combination of expansion, fragmentation, and penetration. I also think, although im not positive, that this round would be good against barriers such as autoglass, and would not have any troubles getting through bone.
Im no expert, and my methods are far from perfect, but I just thought I would share some of my backyard fun.
Here are a few pictures.
