some NOE 150g(156g as cast for me) for supers, to compliment my already cast 230g and 249g for subs. Makes for some cheap chootins. Now to work them up!
$.05 powder(14g H110 estimate, may be slight bit more) $.015 primer (wolf primer, 14$ k, buycheap/stacked it deep) $.025 projectile and powder coat ($.90 LB lead) $.09 per round loaded

I think it's getting better commercially, but will not beat my hand loads. |

I may be misunderstanding you, but the 203gr projectiles are $0.10 per if you buy 2k and the 125gr seem to be running about $0.23 as far as I can find. Edit: oops, forgot to add shipping. |

Ugh. I developed a load using 11.3 gr of 5744 for the 208 A-max. It chronographed at 1050 fps from my 8" barrel, cycled great and seemed very consistent, so I loaded up 600 rounds.
I found out during my next range trip that the powder is not burning completely and quite a bit of un-burned powder is being spit from the ejection port and being dumped into the lower reciever.

With 11.0gr of 4227 recoil felt like a soft push. Accuracy was pretty good at 50m using a Trijicon Reflex with a 12.9 MOA triangle reticle. Dunno on FPS since I do not yet have a chronograph. Next plan is to load some up to test function in my 16" AAC upper. |

Longer bullets would sometimes impact the rifling before being fully chambered as a result. As per the CMMG Website: We are now using +0.002" Head Space Gauges (Both GO and NO-GO) on all our .300 Blackout barrels. After extensive research we have found that this is the new "industry standard" for gas-operated semi-auto firearms chambered in .300 Blackout. This will allow for a greater range of operation compatibility with projectile length/grain weight that is available to this new SAAMI platform. Newer CMMG Barrels don't have this problem. |

Just getting into the reloading game and trying to gather components. I have a line for pulldown powder out of commercial Federal ammo that states equivalence to H110/W296 but start with a 20% reduction. Since I can't seem to find any other data proven powders I'm considering purchasing in the minimal quantity of 8 lbs. If I were to purchase this and begin loading for 300 blk, should I take that start point as 20% off the max loads or 20% off the min loads? From the 1/2 of this thread I've made it through so far I would assume 20% off the max loads but would like an experienced voice on if this is even a good idea.
For what it's worth I plan to only load 125 - 135 grain bullets for supersonic use at the moment as all I have is a 16" carbine gas system. Eventually I plan to work on subs both for this 1 in 7 twist 16" barrel but also for a potential pistol but that may get created. The supersonic loads are my primary task which is why I'd like to collect powder. I can wait on subs until I happen to run into available powder, though I did find something about another powder (currently able to purchase) being the same as Accurate 1680 though I'd rather have the actual thing. As an aside, thank you all for this wonderful resource I'm trudging through. Edit: Maybe I shouldn't have said a word about the pulldown 110/296 since in less than 24 hrs the absurd amount of it is all sold out. Next time I'll just buy and hope for the best. Perhaps that's what I should do with the 1680 alternative. |

Hornady 150gr FMJBT can be found for 0.20-0.22 most places RMR and Wideners are good sources of new 147gr M80's for 0.18-0.22. The lighter 110-125gr bullets that I've seen are a little more expensive and of course they require more powder therefore more $$$. It all depends on what you're looking for in a bullet. |

I'll be starting the 300 blackout loading as my first entrance to brass case loading. When I begin I would consider myself having limited (not thousands) shotshell reloading experience where the name of the game is to stick with the published loads and not deviate at all from what I've gathered. I would feel much more comfortable with the "actual" powder so I guess I may just have to wait until I find something available. At least I have a little stock of PNW 147gr to play with for a bit. Still haven't shot the blackout though, hopefully soon. Once I work some dummy rounds up to check measurements I have a feeling I'll be fine working up loads. Accuracy is my goal, not fps. Accuracy and cycling. I've seen some great information regarding checking for signs of overpressure and hot loads so once I'm comfortable with the creation I'll begin to feel better about using the non-standard powder. If only I could find powders for "standard" supersonic loads. It seems the typical sub powders turn out not so great accuracy in supers from what I've seen around the interwebs. If I land the sub powder first I'll probably end up working loads for both with it just to get the practice though. Initially I'll probably go from start to 0.8 or 1 grain above in 0.2 to 0.3 gr increments, maybe 5 cartridges each load. This seems a solid way to not "waste" or have to disassemble too much. |

I have yet to buy a commercial round for 300BLK...
I have played with a lot of different load combos, but supers that seemed to work for me were Hornaday 147 FMJBT's (surplus stuff from Ballistic Tools) with 17.4gr of IMR 4227, the only powder I have been able to source locally. I would love to find some H110 or Lil Gun to play with...lol 
I worked this up .2 grains at a time and found the best results @ 17.4 pretty cheap to load and acheived a best group of .976" @ 100 YDS from an Alpha 16" barrel. it is a slightly compessed load in LC brass... but seems to burn completely/cleanly with CCI SRM primers and a pretty tight crimp. OAL is 2.110" I'm in the waiting phase for my Form1 to be granted so I can build a can and venture into the sub arena... maybe someone will find this info useful... |

Thank you for the welcome. I'll be starting the 300 blackout loading as my first entrance to brass case loading. When I begin I would consider myself having limited (not thousands) shotshell reloading experience where the name of the game is to stick with the published loads and not deviate at all from what I've gathered. I would feel much more comfortable with the "actual" powder so I guess I may just have to wait until I find something available. At least I have a little stock of PNW 147gr to play with for a bit. Still haven't shot the blackout though, hopefully soon. Once I work some dummy rounds up to check measurements I have a feeling I'll be fine working up loads. Accuracy is my goal, not fps. Accuracy and cycling. I've seen some great information regarding checking for signs of overpressure and hot loads so once I'm comfortable with the creation I'll begin to feel better about using the non-standard powder. If only I could find powders for "standard" supersonic loads. It seems the typical sub powders turn out not so great accuracy in supers from what I've seen around the interwebs. If I land the sub powder first I'll probably end up working loads for both with it just to get the practice though. Initially I'll probably go from start to 0.8 or 1 grain above in 0.2 to 0.3 gr increments, maybe 5 cartridges each load. This seems a solid way to not "waste" or have to disassemble too much. Your decision about dummy rounds is a good one. You need to have confidence that a particular bullet contour and COAL feed in your gun, and that's a perfect job for dummies. The "standard" supersonic powders for 300 Blackout are Hornady's Lil' Gun and H110, and Accurate's A1680, along with others that do better with lighter or heavier bullets. Finding these is indeed problematic, I'm sad to say...I"m still looking for Lil' Gun locally, and it seems to stay out of stock with major online suppliers. Powders that work well for subsonic loads don't do what supersonic rounds need; they burn differently and generate the wrong kind of pressure curve for lighter bullets. I tend to think of "supersonic versus subsonic" just in terms of bullet weight, and that makes it simpler for me. I too am waiting to shoot my 300 Blackout. Between finding components (particularly powders) and finding time to build loads, I haven't even gotten close to taking the gun to the range yet. I really want to build some test loads and shoot them over my chrono, but stuff (today stuff is "oh, and you're on the schedule for Saturday...didn't we tell you that earlier?) keeps getting in the way.

Anyone else notice that some brands of brass seem to expand after sizing? I've got about 5% of my cases not fitting in my Giraud Trimmer and need to be resized...
Seems like its all foreign ammo made in Europe |

Seems like its all foreign ammo made in Europe S&B ATI 09 MKE 08 AZ (Nato Cross) 93 I resized them again, and half still wouldn't fit. Not sure if I need to readjust my die for those casings, but I tossed them. I wasn't wasting anymore time. |

It sounds like you're running into a known issue of the case wall of the 5.56 brass being too thick for in-spec 300BLK brass. If the case walls (now the neck of the 300BLK round) are thicker than 0.013" (I believe it's 0.013 - I'll verify and update the post) you'll likely have problems chambering the round. It's fortunate that your trimmer found the issue for your before you loaded the round. Lake City, Federal, Hornady, Remmington brass have all worked fine for me. Though I try to stay all Lake City for my conversion brass. -Millbarge |

SAAMI specs for a 300BLK neck: 0.334" Projectile Diameter: 0.308" This leaves 0.026" available for the case wall. Divide this by 2 for both sides of the neck and you're left with 0.013". -Millbarge |

One other powder Ill recommend for 150 gr. projectiles is IMR4227. It has performed better than H110 with the 150s in my rifle. And it is widely available in my area You might want to try it.
Curious: has anyone tried IMR 4227 for subsonic loads? |

Curious: has anyone tried IMR 4227 for subsonic loads? I have with 208s and 220s. I can't get them to cycle right out of a carbine length gas system reliably with or without a can. They cycle through my pistol length with a can but I still get a hangup now and then. It is supposed to be close in burn rate to 1680, but it doesn't make one cycle like 1680 will. |
