The bullet diameter after pc is .310. The neck wall thickness is .012. I'm using once fired factory 300blk brass and not converted brass.

After a looking around for a while I think I'm going to order this http://noebulletmolds.com/NV/product_info.php?cPath=88&products_id=1512
I ended up ordering a .308 and .309 which should be here shortly. I'll post back with the results once I'm able to do some more testing. |

Anybody got any information on loads using Sierra 220 grain Pro-Hunters over Accurate 1680? I'll be running them in an 8.5" Noveske with a form 1 can. I've read through several pages of this thread but haven't found anything using this bullet yet.

I'd start at 11.0 grains and proceed according to what the chronograph says. If you don't, listening for the crack can be tricky. |

Guys, pistol powder is a pain in my ass.
I've only been reloading about 2 years now, 300blk got me started, and I shifted to mostly reloading 308 stuff. My biggest turn off to reloading 300blk is that H110 leaks everywhere out of my lee powder measurer and makes the action gritty, and jams up my trickler  .
Any suggestions on how you guys meter/measure/handle your fine spherical powders? |

I have to pull 200 9mm Gold Dots with TB because I don't trust it to throw accurate charges with those fine powders. H110 doesn't do it on mine though, maybe try Lil Gun it's not so fine |

You need a Cast iron powder measure, RCBS, Hornady, Lyman, or a Redding.
All of these will measure ball powder exact with good technique. (H-110 and True Blue are ball powders) Saying "pistol powder" when you mean Ball powder is incorrect. There are ball powders suitable for pistol or rifle cartridges. |

I'll post back with the results once I'm able to do some more testing. I received my NOE expander plugs today and I'm very happy with how well they worked. The .309 plug expands the cases to a little over .308 which is perfect for my .310 bullets. I loaded up 5 rounds using the ogive method which ends up being just shy of compressing 10 grains of RL-7. Initial results look very promising. My cases are no longer covered in soot, I'm not getting a blowback of unburnt powder and my velocity is much more consistent. Average velocity of 5 shots is 970 FPS, up from 950. Extreme spread is 29, down from around 75. The wind is currently gusting upwards of 35 mph so I may have to save any accuracy testing for another day. |

Magpul is making a 300 blk mag,
Product Detail The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in 300 Blackout. Since it’s inception, 300 Blackout shooters have had to use a magazine designed for another cartridge, limiting it’s performance and compatibility. One of the nice features of 300 Blackout is the compatibility with 5.56x45mm parts, but with the magazine it is a compromise to do so. Due to the wide variety of projectile weights and shapes potentially decreasing overall reliability, a dedicated 300 Blackout magazine was a logical step for the PMAG line. In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B also offers a safer way to feed your 300 BLK rifle. When using 5.56 mags, the potential to chamber and fire a 300 BLK round in a 5.56 rifle with catastrophic results requires diligent ammunition management by the shooter. The PMAG 30 AR 300 B’s distinct rib design provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues. Along with optimized 300 BLK performance, the PMAG 30 AR 300 B brings along all of the GEN M3 features such as our next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, a paint pen dot matrix for marking and identification, and a dust/impact cover. • Dedicated, purpose-designed magazine for rifles chambered in 300 Blackout • Optimized internal geometry accommodates the wide variety of bullet profiles used in 300 Blackout cartridges • Distinct rib design provides the shooter a visual & tactile difference from any other pmag to mitigate dangerous cross-loading • Carries forward the physical & performance features of the rest of the gen m3 line From this thread running in GD, 300 blk Magpul thread |

They weren't as accurate as the spire point bullets (Hornady's and Sierra's), but they worked and fed nicely. I believe I had to seat them at an odd OAL, (data's not in front of me), but they were pretty short to keep the .250" diameter at the rib in the magazine. I'm now saving my metric butt-load of 110 FMJs for a .30 Carbine loading project whenever I get some (a large amount of) time, and I've moved to "pointier" bullets for Blackout. |

I have quite a bit of lead from shooting .22 lr into a bullet trap.
I also have some scrap lead and 25# of Linotype. I've got a 1-7 twist barrel for a bolt action rifle chambered in .300 Blackout coming in soon (plus an AR in .300 Blackout). What would be an acceptable hardness for cast .300 Blackout bullets that will all be subsonic. . . And powdercoated? I've seen a BHN of 11-12 for subsonic, but wondering if the powdercoating might let me get away with a softer bullet. |

My supersonic 155 gr 2R cast bullets are "whatever" alloy.
I would guess roughly the same as Wheel Weights. The powder coat process is an amazing bullet jacket. eta, I believe it's more about bullet/bore fit than hardness. I size my 300 blk bullets to .310 with a Lee bullet sizer. Lee doesn't make a .310 sizer, but it's easy to open up a .309 sizer with 400 grit wet/dry sandpaper on a dowel. |

It is both unwise and futile to put much effort into identifying a powder found in a commercially loaded round. It is quite possible that the powder used is not available as a canister grade powder, despite "looking just like" some powder or other that IS available. |

Nothing was spouted, you got a very reasonable answer. Just not the one you wanted.
The way to duplicate a factory load is to measure the velocity of the load. Then load with a powder available to a reloader to give the same velocity. A handloader doesn't care what the factory used. Factory loads are a compromise to function in many different firearms. We care about custom tuning a load to our firearm, not settle for what is commercially available. |

Why do people always spout this if someone asks what kind of powder a factory cartridge has? Maybe people are just curious. The only reason to even vaguely want to know what specific powder is in a particular factory load is if there's something special about that load, such as low flash (or something negative like LOTS of flash), and then only if you want to find out how that "something special" was produced. The way we keep this hobby safe (and avoid well meaning idiots trying to regulate us to death) is by staying VERY safe. Handloaders that blow stuff up because they take shortcuts do not keep us safe. The worst thing I've done in handloading is miss dropping powder in 3 out of 100 rounds of 9mm ammo, which gave me a squib, some powder burns, a damaged gun and a huge sense that I could have done a lot of damage that way. I pulled down all of the remaining rounds and tried to see how I'd goofed. I wound up learning a lot about HOW I was loading, which made me safer and more efficient. I never want to hear about someone who posts here having lost a finger, an eye, or a life by thinking that this hobby is inherently goof-proof. Because it ain't. So I "spout" this sort of thing, hoping I can help someone I've never met avoid hurting himself or others. That's why... |

You are both right. Back in time, way before the internet; this was the difference between a "Handloader" and a "Reloader". The Handloader was all about the most customnest loads possible; the last hundredth of an inch, the last 10 fps possible. The Reloader was about making the best "factory" style loads possible. Work in anything, better than the factory. Bubba just threw shit together. |

Is this the right place to ask about 300 BLK loads using Rainier's 180 RNFP (Plated lead) bullets?
They're about $120/1000 plus shipping (about .12 cents each) Seems like a great low-cost plinking round. Rainier suggests max of 1500 fps... Any ideas? |

Asking if anyone has experience and/or load data for the above. OAL, powder/charge weight, functioning, feeding reliability, accuracy, those kinds of things. Thanks. |

For load data use 180 gr data and work up from the start load.
Develop your OAL with the .250 ogive rule. (covered on page 1 of this thread). If it was me loading them, I would use Lil'Gun. I did have some Speer 180 gr RN's I shot up with 15 grs of Lil'Gun. OAL 2.12. I started at 14.0 grs. With the correct OAL, RN bullets feed fine in an AR in 300 blk. |

Hey guys,
I'm new to the .300 Blackout reloading game. I want to make sure that I am doing this .250 ogive rule correctly. My case is trimmed to 1.360" and I am seating a Sierra 168gr MatchKing bullet. My COAL is 2.078" - 2.080". Does this sound close to being right? |

OAL by itself is really meaningless without more data. If it fits in the magazine, AND if the .250" diameter point on the bullet is in the right spot in the magazine (per dryflash3's pictures), then that OAL is "about right." Sometimes the ".250 rule" only gets you in the close proximity to the final, functional OAL

We need to see the sharpie mark next to the mag bump. |

Anyone converted Wolf gold to 300 brass? Wondering if the neck is too thick, I know Geco brass won't work as I've already tried. I have a ton of Wolf, just want to know if it's worth converting or not.

I have a ton of Wolf, just want to know if it's worth converting or not. Give a few a try and see what happens. In my experience, most of the "neck too thick" issues people have with converting brass has more to do with how they do the forming than the cases themselves. I chop cases, then anneal them before forming. I chop my cases a bit long - long enough that they need a bit of trimming after forming as well. I've gone through a lot of different headstamps that "the list" on 300 BlkTalk says are "no go" because of "thick necks" and not had a single issue. I believe this is because the annealing makes the neck conform both to the sizing die and the expander ball, which should adjust the thickness of the brass in the process. I KNOW that annealing reduces forming effort. |
