NOTE, the archive toggle is set for this thread.
That means you don't have to bump this thread to keep it out of the archives. So copy the link for future reference. dryflash3 As of late there has been quite a few questions regarding the 300 Blackout. With the blessing of the mods I have created this master thread to help consolidate all of the questions and data. Hopefully with this thread we can accomplish a couple different things. First make it easier to answer and find questions, and second gain enough info and data to start building good load data for the database. Please post all your Blackout questions here. If you post data please make sure it includes all of this info: Data should include: 1) Caliber 2) Case manufacturer 3) Case length 4) Bullet manufacturer 5) Bullet weight and type 6) Powder type 7) Powder charge weight 8) OAL 9) Primer 10) Firearm tested in 11) Chrono data (Avg, ES, SD) |

Heads up on case making. Make sure you clean any fine brass cuttings (powder) out of cases before
loading. I noticed the "gold dust" but didn't think too much about it. My gun, 16" barrel with pistol gas, threw fired cases about 10-15 feet at 5 o'clock until it quit working. Finally found the problem causing it to be under gassed to the point it would not eject cases. The carrier key was packed about half the length of the key with brass powder and carbon. It was like concrete. Had to drill it out. I have to admit I really "lit it up" at the range on El Presidente when it quit working. |

I'm finally getting my 220 grain Nosler Ballistic Tip Hunting bullets tonight. I'm going to work up a subsonic deer hunting load with CFEBLK or Lilgun in a 9" suppressed barrel.
Judging by the following data which was gathered with a 16" barrel, I'm going to start at Hodgdon's max loads and work up to 1060fps or pressure signs (whichever comes first). Sound reasonable? Attached File Attached File Attached File |

Ok, I tried loading up some of the 220 ballistic tips and stopped at 2. Not sure what's up with my hornady full size die bit it damaged both bullets. It left a ring around the bullet just below the polymer tip and deformed the bullets. Any suggestions?

And crimp the crap out of the case. Turns out all the moving parts inside the seating die, would slide far enough apart, from the long bullet, to not support eachother. Everything eat its self and went south fro there. Hornady replaced everything and I went with a skinnier bullet up near the tip, so the two parts are slid into eachother to prevent this. My point is it started with a ring in the bullet. I'm sure it's in this thread...someplace. (With pics) |

The loads I showed above were made with RCBS dies. I did notice slight deformation of the bullet, and you can see some refraction of light in the pictures just below the tip.

Can anyone suggest a starting point for the following combo? My goal is to make a supersonic plinking round for a 9" pistol gas AR.
I'll be using 150gr Hornady fmj seated to 2.080, A1680, cci 41, and Hornady casings. Accurate's data states 19.4 grains with a 150gr fmj as a minimum. The thing is, the powder seems very high in the case at 19.4 grains. As I increase the powder charge by .3 grains the OAL grows with each increment and resistance on the lever increases slightly. I don't hear any crunching but this tells me they're probably already compressed at 19.4. OAL was longer at 19.4 than with the dummy round I made while adjusting the seating die. I don't feel safe firing any of these and thought I'd check in with you all first. |

I was having issues with A-1680 filling the case before reaching a full load.
I was at 21.5 grs A-1680. OALl 2.12. I switched to Lil'Gun, used Hodgdon data. I'm using 15.5 grs LilGun with a Hornady 150 gr SP #3031, OAL 2.070. Haven't tried CFE blk yet with this bullet. |

@jgieske
The accurate data I have doesn't list the hornady bullet but a sierra 150 bt at 2.15 col. The Hornady 9th lists the 150 gr fmj at 2.220 col with 15.4 as a starting load. While the accurate load tables show a compressed load your col seems a bit short. |

Yes I tested A-1680 and I posted the load I ended up with.
This was back when A-1680 was very hard to find a couple of years ago. My main use for A-1680 is in 7.62x39, and I didn't find it a good fit in supersonic 300 blk loads. So I quit using it in 300 blk, switched to Lil'Gun that doesn't have to use compressed loads like A-1680. It will work in 300 blk, but not for me. |

I'm getting horrible accuracy from my sub loads, I'm talking 12 moa bad .
Bullets: NOE 247gr cast from straight wheel weights, powder coated and sized to .309". Cases: Once fired factory brass (not converted). Case prep: • Resized so the shoulder is pushed back .002" from a fire formed case. • Trimmed to 1.355" if needed, all pieces are chamfered and deburred. • Primer pockets are uniformed. • Necks are expanded with a NOE .312" expander ball. Load, seating, crimp: 11gr of H4198 for ~1040 FPS. Bullets are seated to the top driving band and crimped with a Lee FCD just enough to remove any bell left from the expander. I'm using a Ballistic Advantage 8" 1/8 twist pistol gas barrel that slugs to .307" which should be perfect. The bullets make a strange "wizzing" sound when fired but aren't keyholing and there's no leading in the barrel. This has been really frustrating and I'm about ready to call it quits. Does anyone have any ideas as to why I'm this accuracy issue? |

I would try sizing to .310 and a little more crimp.
When I started loading 300 blk, I wasn't crimping and accuracy was poor. Started crimping with a Lee FCD and accuracy was greatly improved. Try that first. Look down on FCD, notice the 4 slots in the collet. Adjust crimp so that gap closes half way, and you have what I call a normal crimp. Close gap 1/4 way= light crimp. Close gap completely= heavy crimp. These are my terms/method, good luck. Eta, one more thing. What are you using to expand the necks of your cases? I use a Lyman "M" die. Lyman M die If you scrape any of the bullet when you seat it, accuracy will be terrible. |

View Quote A lot of people seem to do well forming cases with Dillon's sizer and trim die, but make sure you properly expand the necks or you'll have problems. I form my cases the old fashioned way: I chop them to length, anneal them, size them, then trim them. I personally feel that annealing after shortening but before forming gives me more consistent necks. |
