[ARCHIVED THREAD] - Proper load for 5.56? (Page 2 of 2)

Quoted:
Loaded, starting with 63 g data, so 25.5 Varget and only hit close to 2700 PSI, in a LMT Cabine that DID reach 3000 FPS using factory M855 IMHO, I am not going to be able to get near 3000 fps with powders I have and am not that interested in 3000 fps to chase powders. The load was accurate at the short distance I was testing, so I have to see what it does at 100 yards. Edit, read you post is misleading. Im guessing you meant 2700 FPS Done |

So what our saying is that there is no way to get decent 5.56 performance out of the cartridge, and that I'm stuck with the underpowered .223 SAAMI style rounds? If I wanted that I would just by a Bunch of Wolf Military Classic, and call it a day, but I want more than that. There has to be decent powder available, why is the right stuff unobtainable? I just don't see myself buying 5.56 at Scalpers prices about double what normal .223 goes for, only to have factory seconds just to add insult to injury. That's not even speaking of Mk262 when I can find it, my God I would need to take out a loan to afford the stuff in any appreciable quantity. I would want at a bare minimum enough to completely fill an Ammo Can, try pricing that sometime..... Not safely. The simple truth of this: YOU DO NOT HAVE ACCESS TO THE SAME NON CANNISTER GRADE POWDERS AS USED BY LAKE CITY. It's the secret ingredient so to speak, and attempting to hit those velocities is always dangerous, and usually impossible. You have the ability to use something for defense I don't: HIGH QUALITY EXPANDING BULLETS. For the love of god, use them! I'll take a good load with a 65 grain Sierra GameKing over M193 or M855 any day of the week. MK262 is an entirely different story, wish I could load it to spec, but you can still load a damn fine home grown version of it using load books and working up. Use your head, you've got the abiltiy to use great bullets, don't discount that. |

Quoted: I don't know if it's been mention yet since I haven't read through the thread yet. I had a amnesty round from work that was not suitable for use due to being fubard during a weapons malfunction. Anyway, I decided to pull the round and weigh the powder on my 5-0-5 scale. The charge weighed in at 27.2 gr. Quoted: What part of good advice do you not understand! YOU CAN NOT SAFELY REPLICATED THE LOADS PERIOD! You do not have access to the testing equipment and each lot of powder is different! So, give it a rest! EITHER YOU FOLLOW SAFE RELOADING PRACTICES OR YOU SHOULD RELOAD. It obvious that you are NOOB reloader and fail to grasp basic reloading principals! WHAT IS SAFE IN ONE GUN IS NOT SAFE IN YOURS! GIVE IT A BREAK! What's unsafe about attempting to dupe milspec loads? Big deal. You are at, or maybe over, recommended SAAMI max with milspec ammo anyway. Everybody shits when somebody wants to dupe milspec ammo, and trots out the accuracy-over-velocity BS. One of the interesting things about reloading is you can do BOTH. Dats gettin up there if I recall correctly.  |

Quoted: 27.2 grs of powder means nothing without knowing which powder and batch # it is. In any case it's poor form to post in a thread without reading it. Maybe you should leave that part out next time.  fair enough about the powder weight. I was just posting it since I have M855 at my fingertips. |

Why? Accuracy trumps velocity. The savings of being able to reuse the brass is the economy of reloading. Trashing brass on the first 3 loadings is pointless. I'm looking at personal defense not match grade accuracy, it matters not to me if my group is 1 inch, or 4 as long as I hit the target I'm happy, at ranges where that would matter I would probably be better of not engaging or using a better caliber, because that will probably be outside the Fragmentation range, and I'm not interested in expanders in this caliber, Fragmentation is more effective. I'm looking at replicating the military loads because they are proven, and are what I really want, but buying the Federal stuff will break me, not to mention that the XM stuff is factory seconds, I.E. not considered to be good enough for issue, and the Black Hills Mk262 is simply unavailable, and when it does appear for sale it's at a truly obscene price, and there's no way I could afford to by any considerable quantity. If I can't get the same powder that's fine as long as I'm pushing the same projectile at the exact same velocity than I should get the exact same performance, correct? So what load do I need to exactly REPLICATE those loads? This is a recipe for unpleasentness. I'm going to echo everyone else in this thread. Find a better slug, and drive it at lower pressure, more accurately. To replicate mil type loads you need non-canister powders (which you do not have access to), crimped in primers, virgin brass, time and a LOT of experience. The people in this thread know what they're talking about. Listen to them. |

Sierra Game king
Barnes TSX Speer Gold Dot Swift Sirricco(sp?) Hornady GMX Nosler Partition All of these bullets are better choices @ .223 pressure than a 77 SMK at 2800ish fps. I don't know why so many people are obsessed with MK262. The bullet was chosen by the military for accuracy, not some magical killing power. |

OST I love bumping six year old threads. 
I just got 500 77gr SMKs looking to load my own mk262 I have some RL15 and AR comp just waiting on some primers. Anyone have anything AR comp loads? I am glad you said that. I thought I was having nightmares. Wow. 
Since the thread was posted, Ramshot has come out with some 5.56 NATO TAC recipes that achieve M193, M855 performance, IIRC. Those are online somewhere. Also look at third down tacked thread up top of this forum. Then, break it down into AR-15 rifle centerfire. I think you might find some interesting loads there. You might want to get a box of IMI Razor mk262-like rounds to establish a speed baseline using your rifle(s). See this thread, about half way down:http://www.ar15.com/forums/t_3_16/633767_IMI_Razor_Core___New_2000ft_round.html By the way, most of the older comments were correct. Don't expect much brass life, running NATO pressures. |
