I shot some of this through a 22" bolt action Stevens today. Interestingly the average velocity was 2752, only 46fps faster than from a 16" chrome lined AR.
The extreme spread and standard deviation went down (51 and 22 vs 191 and 53 from the 16") and the groups were noticably better. I got 1.5" groups at 100 yards from the Savage, nothing under 2" so far from the AR's. |

I hope I get noticably better than 2" 5 shot groups at 100 yards through the 18" SPR upper I have ordered. But, I still would rather have this over xm193 for a SHTF scenario. I was thinking it would be much more accurate than XM193. |

The two AR barrels I've used are 1:9 chrome lined rack grade barrels, so a nice stainless barrel should perform much better. The 1.5" groups I got from the Savage were from a light contour barrel so don't lose heart just yet. ETA: I need to test them through my 18" fluted stainless AR barrel but haven't gotten around to it. |

At the request of another member I measured overall length and pulled one of these apart.
Cartridge Overall Length = 2.220" Bullet Length = .801" Bullet Weight = 62.2gr Powder Charge = 23.9gr Pic of the bullet and powder:  |

I am very curious as to how this round holds up against various types of barriers.

According to their marketing the round is,
"Designed to defeat the toughest barriers with minimal deflection or deviation for the most intense situations...". http://www.prestostore.com/cgi-bin/store.pl?ref=hotpig27&ct=65207&pd=287456 Is this not correct? Or is the fusion round a different bullet? |

From what I've been able to gather here and on other sites, the XM223SP1 round uses the 62gr Federal Fusion bullet. That is what made me buy it in the first place as the Fusion has performed well on smaller 'big game' and hogs in the past. I plan to try it out this fall when the deer season opens and see how it compares to the two to three times more expensive bonded soft points on the market.

Huh, interesting. I bought a box of this to function test different kinds of ammo in my gun with the heavier buffer spring and buffer. Didn't even know it was a fusion bonded bullet. Sounds good to me.
 Will post accuracy results when I finally get around to testing it. |

Any results so far? How many people have chron'd this load?

No chrono info however I received some interesting info (and a chart!) from Molon about this load after asking him about my observation of my zero with this and 8126N having the same POI.
He indicated that this and 8126N have almost the same trajectories. 50 yard zero on each will be the same, TAP will cross again at 200 yards and XM223SP1 will cross at 210 yards. They stay within about .2" of each other out to 125 yards and increase slightly from there. I hope that makes sense. I sure appreciate it as these are my duty loads now, 4 mags of 8126N and 2 mags of XM223SP1, and I don't have to fret over different POI. |

I have posted various velocities out of various barrel lengths throughout the thread but here is a recap: 7.5" 1:9 chrome lined: 1923fps 11.5" 1:9 chrome lined: 2310fps 16" 1:9 chrome lined: 2706fps 22" 1:9 unlined: 2752fps |

I sure appreciate it as these are my duty loads now, 4 mags of 8126N and 2 mags of XM223SP1, and I don't have to fret over different POI. Have you shot both rounds out of your rifle? Even though the trajectories may be the same once zero'd, they may not have the same ZERO fired from your rifle. For instance, the XM223SP1 may be 1" high or low at 50 yards when your 8126N is zero'd. At 200 yards this could be much more. While I think you would always be at minute of man out to 200 yards with most any decent quality ammo once your sights are zero'd with decent ammo, it may not be as close as you would like for precise shooting. I mainly shoot to prepare for hunting. I ALWAYS shoot multiple groups of any ammunition I am going to be using to verify POI at least at 100 and 200 yards. I'm still waiting on my upper to start sending some of this downrange. |

Yeah, I observed it first which is why I asked Molon.
I agree that I should try it to 200 yards but I'm limited to 100. |

So is the accuracy of this generally better or worse than the Mk318?
