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) |

Quote HistoryOriginally Posted By craig24680: Have a 300blk bolt gun on order to be used for hunting deer and suppressor plinking. Are magnum primers necessary or just added insurance for semi's? I've run quite a few subs with pistol primers. Short answer for supers is it's very unlikely you'll need magnum primers. |

Tested 11.8 gr of AA1680 today.
SMK 220 gr New FC brass (didn’t resize) Rem 7.5 primer Lee factory crimp BA 10.5 barrel (or 10.3 forget which) Form 1 can (freeze plugs) About 2 MOA at 50 yards.

That’s so far ahead of where I was yesterday that it’s shocking, basically the inverse from yesterday. Just need to figure out how to estimate hardness and maybe try to find some source of tin to add to the alloy. |

Just need to figure out how to estimate hardness and maybe try to find some source of tin to add to the alloy. Powder coating make lead hardness almost not matter. I use aprox WW hardness for all rifle bullets. No leading.  Look around for a cheap hot plate, the best way to pre heat molds. Anytime mold is not casting it's on the hot plate. I run it at the mid heat position. |

Talked to FatMcNasty. He said 10.5 gr AA1680 with COAL of 2.210. So I started at 10.0 and did a run of 10. I also did a run of (10) 10.3 gr. Tomorrow, I’ll roll some more runs going all the way up to 11.5.
My rifle has the 12.5” AAC branded upper. ETA: Decided to only go 10.0, 10.3, 10.5, 10.7, and 11.0. I’ll try to find some time this week and see if I can get to the range for testing. My birthday is next week. Wife mentioned one of the molds I showed her (RCBS 311-130 SP), if only I could find it in stock! |

I don't think I have a keeper in the entire initial run I did this morning (they'll be shot for function and EARLY load development). I'm adjusting my technique and I'll start again. ETA1: Ok, here is how I ended up.. took a wire mesh and bolted it to the pan. Now they stand up. https://www.AR15.Com/media/mediaFiles/71141/F5F7BB51-187C-4ADD-90AC-891E197DDA35_jpe-1391020.JPG ETA2: early runs on the left 3. Last two are later runs. https://www.AR15.Com/media/mediaFiles/71141/1FC54939-0DCF-4907-BEE5-2FEFD3AFDDB4_jpe-1391035.JPG
Also, fwiw I use powder from Smoke over at castboolits.gunloads.com. Good powder makes a difference. Especially black. |

Leave off the $.03 gas check and you shoot patterns instead of groups. I have found if a bullet is designed for a gas check use one if you want accuracy, or use a bullet designed without a gas check. Not everyone will agree with me, just reporting what I have found in my testing. Good luck. |

My PC bullets don't lead in 357 through with full H-110 charges in a Marlin M 1894. Same in 44 mag with hot through a Redhalk. I have one pistol mold that uses gas checks, a Lee 6 gang 310 gr. Shoots horrible without gas check. |

Had a chance to chrono some 300 Blackout cast lead loads this weekend.
NOE 230 coated with Hi-Tek and 9.7 grains of IMR 4227 averaged 1043 FPS in a 9" barreled AR. Probably gonna drop these to 9.5 and try again. |

Went out and tested the 300 AAC subs out of my 12.5” AAC factory upper. (I eventually want a 9.5” version as a companion to this one)
5 groups of 10. Half of each group with suppressor attached, 1/2 without. All weights are AA1680 powder charges under 247 gr NOE cast and powder coated WW lead. 10.0 gr no can- cycles perfectly, did not lock open. W/can- same 10.3 gr no can- cycles perfectly, did not lock open. W/can- same 10.5 gr no can- cycles perfectly, did not lock open. W/can- same 10.7 gr with and w/o can cycled perfectly and locked back. Stayed subsonic (roughly sea level, 81* F) 11.0 gr with and w/o can cycled perfectly locked back. Stayed subsonic (see above) So, I’ll probably just roll a bunch with 10.7 gr charges until I buy or borrow a chrono and see how close I’m pushing them. |

Has anyone loaded Everglades 200gr with A1680 or Lil Gun? Ive been trying to poke through this thread but there is so much information I probably already went past it without seeing.

The reviews on the Everglades page have multiple charges listed for 1680. https://www.evergladesammo.com/300-blackout-220gr-plated-bullets.html Link for review purposes only. |

I haven't reloaded in a number of years, but I went and bought myself a 300 AAC pistol, so here I find myself looking at dusting off my Lee Pro 1000.
Looking to first load up cheap training ammo, where are the best deals for components? I have PLENTY of .mil primers for 5.56 and various powders (packed away, I don't even remember what I have anymore), so hopefully I can utilize that. I plan on getting a can and shooting subs, but for now I'll train with whatever is cheapest/easiest to produce. Not interested in making my own bullets though. I bought a few hundred rounds of ready ammunition, will be using the brass off of that or buying more brass (not going to trim my own brass). |

You’ll need some magnum pistol powder like W296/H110, lilGun, or other similar intended for magnum pistols (CFE Black is another choice). 147 gr pulls are one of your cheapest bets for supers. You can also sometimes get the Speer 125gr TNT for around 13 cents/ea. Subs? I think people like Everglades heavy bullets. Hunting or HD, Barnes TACTX 110 and 125 are the gold standard. |

For the 147 grain pulls, what is the favorite source for those? Quick google search yields a lot of OOS situation. |

Natchez Wieners Brownells Midwayusa And probably 10 others I’m unaware of. BTW, I’m using 1680 for my subs, but find a modern manual or dig through some of the official online sources for a starting point (powder, primer, bullet combo). |
