I am limited to the following powders suitable for 300 BLK: Win 296 (same as Hodgdon H110) Lil' Gun 5744 XMP I also have these powders on hand: Vihta Vouri 3N38 and N-350, Hercules 2400. Again, I am only looking to shoot these subsonic & mostly suppressed. The barrel is a 16" Wilson Combat that has the carbine gas system (I am not sure what size the port is). Cases are both factory 300BLK and converted 5.56 cases (mostly LC). Frderal large rifle primers. Can is an old AAC 762. These pulled 180 grn SP bullets fed fairly well when I shot them as supersonic; I used the Win 296 (I think around 16 or 17 grains) and loaded them to the maximum OAL that would fit in my biggest magazine (an H&K). I did get one "nose dive" into the feed ramp. Anyway, given my gas system, what powder would provide the best functioning? I know the charge will need to be around 10 grains or so; anyone have a Wilson 16" like mine & can suggest a charge? Thanks! " |

I loaded 5 190's with 8.5gr of lil gun and 2 of the 3 had supersonic crack. I will drop it to 8.2 and test. All 5 functioned perfect with BHO at the last shot. I am running a 16" with a pistol gas system.

I am new to this cartridge, and it would be nice to have a list of part numbers so when I go to the local sportsmans warehouse or Cabellas I know I am not buying just any old 308 bullet that wont work properly. So far I have found the Sierra Matchking 2121 seems like a useable bullet. We normally go buy weight, brand and shape when describing bullets. |

When do you anneal?

Goos results seem to be very easy to obtain...at least from what I have done so far...with the exception of bullets in the middle of the load range...I have no real use for those any way. |

No, I do not anneal. I don't have the proper equipment for it. If I did anneal it would be between step 9 and 10 on my list. These are my steps to form a 300 BLK from a 5.56 case. My follow on reloading steps after this will be a bit different. I've done it different ways but this particular method has yeilded my best results and seems chronologically correct in my scheme of doing things. |

i don't have usgi mags, only pmags. Using this pics from the first page, is the bump in the usgi mag in the same place as the guide rail in the pmag? i chronoed my first reloads today and they are a little long. They fed really slugishly and i noticed that the bullet was rubbing the "guide rail" inside the pmag, so there was a little binding. So can I use the same concept of aligning the rail in the pmag to where the bullet measures 0.25"? I dont have a usgi mag put side by side with a p mag to see if they are in the same place. I am loading SMK 220gr. and case is trimmed to 1.358" converted from .223 brass using Noveske 8.3" Thanks. |

Nismo542, my mags are locked up in a case behind way too many items to move right now, but I'm going to say yes they are in the general same location. What that feature is for (from my understanding) is to help pre-center the bullet to the chamber when being pushed forward, so it would make sense to keep it in the same location as the original magazine design.
------------------------------------------------------------------------------------------------------------------------------------------ Now for a couple questions of my own, when I ask these let's ignore the fact that is hard to find things available right now, trust me I know. Unless I'm blind, I haven't seen any real mention of it. What dies do y'all use? I've always used RCBS with my hunting calibers, but looking at all the options with this round. I may choose to resize .223 shells, so I'm looking at that option as well with my choice of dies. Secondly, has anyone possibly loaded any 162 grain AP rounds? Specifically ones like shown below. If you have, can you give details on load data.

Has anyone tried loading Berry's Plated 110gr or 123gr 7.62x39 (their nomenclature, not mine) as a subsonic load?
Eta: ...after running them through a .308 bullet sizing die.

I wouldn't think the barrel would be a big deal, but the dies or casings might not like it. But I haven't loaded any, so just an opinion. |

Yea, I looked at Midway to see who all is making dies for the round and all but the crimpers were out of stock. Not that I'm really in a hurry for it, though. Hmm, well that sucks. I have 25 put up and was thinking about loading them for the Blackout. |

But they'll stay where they're at on my loading shelf until I get another .308. That is unless I could possibly find a load for the 300 that would put it to the intended use. |

Ok so I am running a 8.5" 1/8 Rainier Select barrel. The only loads I have fired are 220 gr. SMK over 11.5 gr. of IMR4198 as directed by the Hodgdon load chart. I am also using the Wolf QQQ-SR556 primers which as I understand it are pretty much identical to the CCI #41.
I seem to be getting some horizontal stringing and maybe a slight yaw of the bullet at 50 yards. Curious if you fellas think I should try different powder combinations or maybe step down to the 210 SMK to achieve better accuracy and stabilization? I really don't want to kill my suppressor with a baffle strike and had read that the shorter barrels in 1/8 twist may not like the full 220 gr. bullet. I have Win 296, 4198, and Lil Gun on hand. I didn't build this thing to shoot supers although I will probably mess around with them for deer/plinking. ETA - Upper constructed post Dec 2012 at normal prices..... Had to do some searching though let me tell you.....

Can you use round nose 30 carbine bullets(.308 dia) to fire form 300 blackout case? Captain Howdy's post about unfired coverted brass may not be as accurate had me thinking. I did some search and some had feeding issues, but if it's just to do the final forming, loading one at a time is no problem. Would hate to spend on some good rounds if they aren;t going to be accurate the first time aroung. Found some 110 grain armscor for about $12 per 100.

My formed cases were fine on the first firing after forming.
But I annealed the cases and that made a difference for me. My first outing with formed cases and not annealed was not pretty. (accuracy wise)

The facotry cases arrived from Midway as 1.360" so that is what I trim everything to. |

Would hate to spend on some good rounds if they aren;t going to be accurate the first time aroung. Found some 110 grain armscor for about $12 per 100. They are pretty short, haven't shot these yet. So don't know how they will do. Hornady 110 gr JRN. I do know my rifle will feed 180 gr RN's. If I were buying bullets to fireform cases, I would get 147 gr FMJ's. Cheaper if you can find some.

In the 5th post of page one there is an AA load chart... It tells me that the italized numbers indicate a "compressed load." Does this mean that it has the potenial to hurt my weapon?
I was planning on working up some 147/150 FMJ hot loads with A1680. The help is always appreciated... |

I am running a 16" with a pistol gas system. EXACTLY what I was looking for! I just loaded some 180 grn SP flat base (not 190 grn) over 8.28 grains of Lilgun. I also have the 16" barrel, but mine has the carbine gas system. Hope they feed and function well. This is the 1st adventure with 180 subs; last time I just loaded a few 220 SMK OTMs over W296 / H110 - but those seem to work for everyone. The 180s (with your data for reference) should be subsonic and thus really quiet. Have to wait a few weeks to get out to the shooting range to try them though. With a carbine length gas system I doubt you will get 180s to function subsonic. Well thats just sad. I guess when I get out to the range to try these subs in a few weeks, I'll add lots of oil to the bolt and carrier 1st. Maybe that will help.
Also, my barrel's a Wilson 16" with the CARBINE port - but I will be using a batfe registered AAC brand suppressor. Having a legal supressor might give the gun a better chance of working - but we'll have to wait a few weeks. |

Published compressed loads are called out so that you know the powder charge is not a mistake and the case will be full of powder and the act of bullet seating will compress the powder. Fast burning powder don't fill the case completely, slow burning powders with top charges will. No harm will come to your weapon. Just do the normal work up and don't fear compressed loads. |

Ok.... So I ran some 220's with 9 gr of Lil Gun and it shot really, really well.
4198 is not a good powder for short barrels and the heavy bullet. |

I'm casting some 230's with the Lee bullet mold. Do you think I should just run it with 9.0 gr of Lil Gun to start with, or drop it down .1, .2, or so? (Please be gentle with the n00b reloader...) |

Since no one seems to have advice for those of us with pistols or SBRs, I broke down and ordered QuickLoad. That should help with a few of my projects. I'll try to remember to post findings.

That'd be cool. I'm running a 10.5" barrel on mine. Thanks. Need to get off my butt and load up some 175s with Trail Boss and find a good subsonic load with it. Still waiting on my 1680 to come in and I have 9 lbs of TB I use in my .308 sub loads. |

I can't really say as I don't know anything about how casts affect pressures. My guess would be follow load data for the 230 that Hodgdon has posted on their site. |

I can't really say as I don't know anything about how casts affect pressures. My guess would be follow load data for the 230 that Hodgdon has posted on their site. they have 8.7 of Lil Gun listed to go with the 230 grain Berger Tactical bullets. Those bullets are 1.602" in length, and the 230 grain cast bullets are 1.363. If I load them to an OAL of 2.26", then there won't be as much of the bullet in the case with the cast as there would be with the Berger bullets.... I guess I can start with 8.7 and go up from there if need be. The 220 grain Sierra HPBT bullet I can't find the length of, but Hodgdon says to load them to 2.26" as well. They say to load 9.0 grains of Lil Gun with it, though... I'll just play with it once I get my powder and see what will function correctly (cycle, bho on last round, etc.). I will use a lighter buffer than the Spikes buffer I currently have setup in the SBR, though. |

I don't know the Lee bullet profile, but I'm guessing you'll have to load them shorter than that. |

I know that even with the 220 SMK they want to bind up on the sharp edges of the barrel extension now and then. The CS flat wire buffer spring all but eliminates the binding but you still get the little gouges in the bullet. If the lead bullets just stop in the grooves of the barrel extension I would recommend taking an India stone to the sharp edges and just knocking them down a SMALL amount...... As in just barely raidused instead of angular. I don't know how much those little gouges affect accuracy within 100 or 150 yards with subs but it may be enough to warrant a closer look. |

I hadn't even considered the feed ramps. I was only thinking about the ribs in the magazine, so there's something else to verify. |

Quick question. Does anyone know the link to the guy that sells the little adapter block for the harbor freight cutoff saw for cutting down 5.56 shells to form for 300BLK?
I have this with Rocketman's adapter drawing, but was looking for the one where you push the brass through instead of clamping and unclamping. |
