I was having issues with my brass swaging my cast boolits to much defeating my sizing them to .310, tried an M die and it was still swaging them down to much(I am running a relatively soft alloy)
swapped the Mdie core to this and its been  ever since
Buffalo Arms plenty of neck tension and pulled boolits are still .310 edited to add: it has a long .308 section then the .310 is roughly .25" long and it will bell the cases if you so choose, I add a slight bell |

Today I received my Harbor Freight 2" cut off saw that I ordered about 2 weeks ago. I tried to get it at the store but they told me it wouldn't be available anymore. After I went on online and ordered it they said it was on backorder but it shipped on Oct 17 and today I got it. I also bought the jig from Squirrel Daddy. As soon as I got it, I put it to work cutting 5.56 cases for the first time. Works good.

Quick question for you vets. I'm building a 300blk pistol in the 8-10 in range. Most of the load data I've seen has been for 16in barrels. Am I wrong to think that these loads are a decent starting point, backing off 5 or 10% grains? Or do the shorter barrels like completely different powders? I've been looking like crazy for h110, w296,and lil gun but haven't had any luck. I did manage to get some alliant 2400 to experiment with when I get setup.

Use the same powder, begin loading at the "start" load level as per a published reloading manual. (start load is the lowest charge shown)
Good luck on your powder hunt.

I have 147 grain Winchester FMJs to play with (can't find 125s or 130s in stock where I'm looking), and some H110. I expect to have some fun with this when I get/make the time to put it all together. |

Got another noob question for you guys. Since I'm on a tight budget I've been taking a hard look at the lee challenger kit. I figured I'd start with a single stage and get all the fundamentals down before diving in too deep. Can I use say rcbs or hornady dies on this press? What's recommended? I've read that a few people haven't had good luck with lee 300blk dies, and others have had no problems.

I've read that a few people haven't had good luck with lee 300blk dies, and others have had no problems. Standard reloading dies work in all standard presses. The Challenger is a standard press, and a good starter press. You should also be able to use (just about) any shell holder in that press too. I can't say anything about Lee's 300 Blackout dies, but their other dies that I do have experience with have been quite capable. Good luck, and enjoy. |

When I have looked at both Midsouth and Powder Valley they have been out (same with Graffs and several others). I haven't been camping online to look for bullets, but getting started with loading on 300 is not really dependent on these lighter bullets; it would just be nice to have 'em. |

Thanks for the reply, I'll keep that in mind when I'm shopping for dies. Btw, midsouth has a 500 count pack of speer 125gr tnt's in stock right now. No 100 packs though. Good luck. |

I really like 4227 with the Nosler 125s
Clover leaf with 5 shots @ 100yds. You'll be happy with it when you work up the load. |

Still experimenting with various charge weights to find the "sweet spot" for my Wilson Combat barrel. The powder seems to peform well and generally accuracy at 100 yds is around 1.5 to 2.5 MOA so far. The rifle cycles perfectly with this powder. No FTEs and locks back on last shot. So far my loads are generally in the 90 to 95% of max range. My carbine-length gas port has been opened up to 0.120". Having good luck with H110, W296, and IMR 4227 powders. |

Figured I'd repost this here, from the polygonal rifling thread:
Box o' bullets: 
Typical bullet before seating: 
Pre-seating bullet diameter: 0.3088" (remarkably consistent around the bullet) Pre-seating case neck OD: 0.3298" (one spot, marked for consistent measurement) Belled with Lee tool to 0.3342" (about 0.005" of bell) allows the bullet to sit in the case mouth on its own easily: 
Notice that the bullet is not well aligned with the case. After seating, runout from the case head with the face of the head as a secondary datum (used setup in lathe trimmer) was 0.002", which is perfectly acceptable. Bullet seated to Col 2.135", leaving just a smidgen of the step above the case mouth: 
Crimped with Lee taper crimp die to remove bell, case mouth OD 0.3332" (~0.0034" of neck tension), then pulled with RCBS collet puller: 
Pulled bullet: 
The pulled bullet had no visible damage to the polymer coating. There was no measurable difference in diameter in the bullet after seating and pulling. These function just fine in my AR pistol with pistol length gas system with IMR 4227 and AA1680. Haven't tried them extensively enough in my carbine yet to say whether the gas system length might have an effect.

How much are you paying for those? Those are the exact bullets my friend makes, except with a powder coat or epoxy coating. I only ask because you can probably makes those MUCH cheaper then what you are paying. |

How much are you paying for those? Those are the exact bullets my friend makes, except with a powder coat or epoxy coating. I only ask because you can probably makes those MUCH cheaper then what you are paying. I believe they're something like $0.12-$0.14 apiece, IIRC. I don't cast bullets, primarily because I don't have a source of lead (I've looked around my area as much as possible, and come up empty), and there's a point at which my time is worth more than my money, and bullet casting goes past it. |

$40 per 250 count plus delivery from Missouri Bullet Company. It's 36 per 250 if you don't get the Hi Tech coating.
They do offer a discount for first responders, call before ordering to get the code. |

Seriously, I am curious how much powder you're getting in that case, and how you keep from having the powder (piled up at the bottom of the case) get in the way of seating the bullet all the way.

Those look excellent! Pretty good price too! What twist rate is needed to stabilize the 245gr? I have a 10.5" 1 in 8 twist... Does those require a 1 in 7 to stabilize? Thanks. |

They're subs, so I'm only using 9ish grains of 4227. Fits just fine. Originally Posted By drfroglegs:

At 1050 fps, the Miller formula puts them well in the stable range at even a 1 in 10" twist (a lot of 300 blk barrels are 1:8 just to make sure to stabilize the longer bullets). I haven't seen any keyholing out of my 10.5". My loads are measuring right between 1000 and 1050 fps. |

If the OAL is correct, flat nose bullets will feed fine.
I've used 30-30 FN and plated FP's with no problems in my AR. If you need help setting OAL, see page 1 of this thread for my post on how to set OAL for any bullet in 300 blk. Good luck |

I'm looking to load some subsonic 300blk. Only issue is I don't have a chronograph.
Anyone have a decent method for load development without a chrono, or.....should I break down and get one? Shooting an 8.2" noveske. Plan on....whatever bullets are cheapest, likely 208gr Amax. I may try loading up some recipes that others have posted. I've got 1680 and H110 to play with, so there should be some decent data out there for those. There is pretty much no way I'm blowing anything up dealing with subsonic, correct? I should be way below any pressure limit from what I understand. |

Thanks for posting up those polymer coated 245gr bullets. I'm going to order me some next week and give them a shot (pun intended). Have you shot them with a suppressor yet? It looks like it will be fine at preventing leading, but I wasn't sure if you, MBC, or anyone else has tested that yet. |

That is you can load a ladder and hear when the rounds start going supersonic. |

That is really Not the best way to find a subsonic load. One should start above the speed of sound and work down, otherwise one risks a secondary explosive effect.

You can still start above the speed of sound and work down while using your ear to test subsonic.. Those two approaches are not exclusive. I have a chrono, but if I didn't I would definitely just work my way down and listen to when it stops the supersonic crack.. So do both suggestions :) |

Vegitan is running a test on precisely that, using them in a liberty mystic that can be taken apart, in the polymer bullets/polygonal rifling thread. |

Had a migraine yesterday and didn't get the reloading done. Will get them loaded tonight and if light permitting get them shot too.
Confirmed Remington 6 1/2's work just fine for subsonic loads. Figured they would but now I got a way to get rid of those primers. |

Figured they would but now I got a way to get rid of those primers. Great, in very curious to hear how things go. Got a specwar in jail and would hate to ruin it on its inaugural shoot! Can I ask a favor? Do you mind measuring the length of the bullet (projectile). It's not listed on their website. Also, does anyone know the BC? I want to put it into my strelok program and see what the ballistics look like. Thanks! |

I am opening the can this weekend, got the last of the box of 250 loaded tonight. I will post pictures tomorrow of the baffles but won't clean the can until after 750 maybe 1k rounds. I have an Osprey so I can leave the Mystic for just this experiment. |

Cool video documentation. And you can clearly see the subsonic loads are short-stroking the BC. Quote HistoryOriginally Posted By eric10mm:

I ordered some of the Hi-Tek coated 300 blackout boolits from MissouriBulletCo, should be here on Monday.
I started looking into the Hi-Tek coating, and powder coating for comparison, and found a really interesting article. This guy used lacquer thinner to disperse traditional powder coating powder (harbor freight) and then baked it like normal. Claims it easily sticks to the boolit and shoots great. http://www.tngunowners.com/forums/topic/66713-powder-coating-the-easy-way/ Has anyone tried this with the 300blk boolits? I ordered the lee mold as well, that should be here over the weekend. This has the potential to be a dirt cheap method for producing subsonic ammo. If you take away the cost of bullets/boolits (I get free brass), I would be able to make loaded subsonic ammo for $2.50/box of 50 ($0.05/ea). |

So just started on Sunday loading for the .300blk. I primed 100 cases (for the first time ever I had a primer blow up next to my face using a hand primer) using 7 1/2 primers. I plan to do 50 using 1680 and 50 using 5744 subs. Using 210 match. Also breaking in the new chronograph since I am now loading subs. Any suggestions? Going through an MPW 9"

Do you have any more info on the method? What tumbler? A HF rock tumbler or do you just shake them by hand? What is a "hardware cloth"? This guy claims that doing this method works great because the liquid gets into every nook. The powder method does look easier though! Oh, and my mold came in today!!! |
