So,
I've run into a few cases of xm193 840 round cans on strippers... I have lots of 855 but like 3 full cans on 193... Any reason anyone can think to not just sell all my 193 and load everything with 855? Bret |

Some say m193 is better. Unless you are fighting soviets with body armor. Or so "they" say. Not "them": |

I usually don't get rid of things...and I have a few rifles that have had a steady diet of 193 ove the years... Just for plinking...or sell it for the insain prices... Bret |

The problem with M855 is that if you are shooting any tactical matches where they use steel targets, they won't let you use the green tips.
I'd rather have M193. And it has worse terminal ballistics than M193, and many ranges won't let you use it, and it's not compatible with 1/12 twist barrels. |

So,
Yes, I have 20+ cases of 855... What I found was a few cans of 193... I'm thinking of selling to finance a couple of things... I thinkm193 and 855 would both fetch top dollar on gb... It's just if there is something special that 193 does that 855 don't... I have 2 full cans of 840 rounds each... My debate is, save the 193 cuz it does something 855 can't... Or just dump, sell, the 193... Ive got good ammo as well...but people seem to go ape shit over this stuff... All my large qty of ammo is on strippers and sealed from mfg... So, can anybody give a good reason to sell 855 insted of the 193... I'll have to take a look...but I don't think I have any 1:12 bbl... Bret |

I'd rather have M193. this ETA in a AR, for my beltfeds I would use the 62 grain, but that's it. Why? Bret It (M855) was actually meant for belt fed squad automatic; if memory serves me correctly, M855 has better penetration at longer ranges - something to do with the steel core construction shifts the center of gravity, making the projectile pointing forward longer throughout its flight. I think against steel helmet M855 penetrates at 1200 meters (outperforming M80 ball), while M193 defeats steel helmet at 500 meters. The military wanted uniformity in logistic, hence everybody gets M855 (although for the longest time M193 and M855 were issued together, hence the green tip ID). |

The M193 is more effective than the 855 under a 100 yards or so...has more yaw which creates a bigger wound. Above that range 855 is the way to go. 
Actually from a 20" barrel M193 will still fragment out to 150 meters if I remember correctly. I believe it will still yaw at 2400 FPS, which is what, 200 + meters? Regardless, it is the fragmentation that creates the destructive permanent cavity, not the yaw. M855 penetrates better than M193 at extended ranges, that's it. Also, remember that fragmentation is a function of statistic. So is penetration depth where fragmentation occurs. A percentage of projectiles will penetrate at a certain velocity range and some will not fragment at all. The same with depth of penetration before fragmentation occurs - some projo will fragment sooner than others. If generic .223 / M193 / M855 is all you got then it's all you got - shot placement still trumps other factors. But they are not the optimal choice. Heavier OTM's and TAPs are the way to go for defense, IMHO. |

I think it wasn't even against body armor - I believe the test was conducted against steel helmets and NATO plates (mild steel, thickness??) What will happen if we start fighting enemies wearing plates? M995 as general issue? What about us lowly civies? What's going to happen if home invaders start wearing plates? Defend our homes with .338 Lapua or something? Maybe those solid copper 4XX Rigby meant for Water Buffalos? LOL! |

Hard to plate their heads... and if they wear steel/Kevlar helmets... shoot with a big enough caliber to penetrate it or for the impact to break their neck. They had better have crotch and ass plates too!

Flash I think if home intruders start wearing plates, a shotgun will be a better home defense choice than an AR. Easier to hit those heads with scattering bird shots (I know buck shots are better against torso because of penetration, but remember they're wearing plates now) than a single projectile, no? Maybe buck shots against the crotch?  
Sorry about the hijack, OP. |

Flash Neck shots like on does ;), 2nd the crotch plates, I'll take a wounded guy over a healthy one shooting at me any day.. especially if I can sever a femoral.. 90seconds to wait for em to end. |
